This study aims to analyze how restaurants' collaboration with mobile food delivery applications (MFDAs) affects product development efficiency and argues that technological capabilities moderate relational ties impact the joint decision-making and development efficiency of restaurant products.

A product development efficiency model was formulated using a resource-based view and real options theory. In all, 472 samples were collected from restaurants collaborating with MFDAs, and partial least squares structural equation modeling was applied to the proposed model.

The findings of this study indicate three factors are critical to the product development efficiency between restaurants and MFDAs; restaurants must develop a strong connection with the latter to ensure meals are consistently served promptly. Developers of MFDAs should use artificial intelligence analysis, such as order records of different genders and ages or various consumption attributes, to collaborate with restaurants.

To the best of the authors’ knowledge, this study is one of the few that considers the role of MFDAs as a product strategy for restaurant operations, and the factors the authors found can enhance restaurants’ product development efficiency. Second, as strategic artificial intelligence adaptation changes, collaborating firms and restaurants use such applications for product development to help consumers identify products.

Many restaurants offer high-quality service to their customers, hoping to provide memorable experiences that influence their loyalty and electronic word of mouth (eWOM). However, consumers' memorable experiences do not always imply positive eWOM. This study aims to (1) verify the direct impacts of the perceived quality by consumers of casual dining restaurants on positive emotions, negative emotions and memorable experiences; (2) investigate the impacts of memorable experiences on the propensity to loyalty and eWOM; (3) test the moderating effect of consumer behavioural engagement on social networking sites (CBE-SNS) on the relationship between memorable experiences and eWOM.

This survey included 475 university students in Brazil. Participants answered an electronic form about their experiences in casual dining restaurants. Structural equation modelling tested the hypothetical model based on the stimulus-organism-response (S-O-R) theory (Mehrabian and Russell, 1974).

The quality perceived by restaurant consumers (stimulus) positively impacts their memorable experiences and positive emotions and negatively affects their negative emotions (organism). Memorable experiences positively impact the propensity to loyalty (response). The CBE-SNS moderates the intensity of the relationship between memorable experiences (organism) and eWOM (response).

This study is the first that demonstrates the relationships between perceived quality, positive and negative emotions, memorable experiences, the propensity to loyalty and CBE-SNS and e-WOM in restaurants. Casual dining restaurants must offer their customers services with high perceived quality, positively impacting their emotions and their memorable experiences. Finally, restaurants must create strategies and actions to increase the CBE-SNS to encourage them to share their memorable experiences through eWOM.

With the growing popularity of social media, it has become common practice for consumers to write online reviews to share their opinion and experience as well as consider others' reviews to inform purchase decision-making. This study investigated how online review sentiments towards four key aspects (food, service, ambience and price) change after a restaurant is awarded a Michelin Star to shed light on how the award of a Michelin Star affects online reviews as well as what factors contribute to positive online restaurant reviews.

The authors conducted a sentiment analysis of online restaurant reviews on TripAdvisor. A total of 8,871 English-written reviews from 87 restaurants located in Europe were extracted using a web crawler developed by Beautiful Soup, and data were then processed using Semantria.

The study findings revealed that overall sentiments decreased after restaurants were awarded a Michelin Star, in which service sentiment was the most affected aspect, followed by food and ambience. Yet, price sentiment showed a prominent increase. This provides valuable insights for Michelin-starred restaurant operators and owners to create a unique and compelling gastronomic experience that triggers positive online reviews.

The results of this study argue that consumers tend to hold higher expectations for this type of upscale restaurants given its recognition and quality assurance, so they are more likely to have negative feelings when their expectations are disconfirmed. Therefore, restaurants should continuously improve their food and service while paying attention to small details such as ambience, through creativity and innovation. Also, high-end restaurants, especially Michelin-starred restaurants, usually have the edge in premium pricing, yet competitive pricing may backfire considering its perceived luxurious values.

This study analyzed changes in customer sentiments when a restaurant is awarded a Michelin Star through text analytics. Through the lens of online restaurant reviews, the study findings contribute to identifying aspects that are most or least affected by the award of a Michelin Star as well as highlight the role of ambience in customer satisfaction which might have been overlooked in previous studies.

隨著社交媒體日趨普及，消費者出現一種常見的做法，就是在網上書寫評論，分享他們的意見和體驗，他們也會參考其他消費者的評論，以在購物時能作出知情決定。本研究擬探討當餐館獲得米其林星級時，消費者對它們在四個主要方面 (即食物、服務、情調和價格) 的網上評價會如何改變。我們藉此能更容易了解、餐館獲得米其林星級會如何影響其網上評論，以及是哪些因素、會為這些餐館帶來正面的網上評價。

我們對貓途鷹平台上的網上餐館評論進行情感分析。透過BeautifulSoup 研發的網絡爬蟲，我們取出位於歐洲87間餐館、共8,871個以英文書寫的評論，並把這些數據以Semantria加以處理。

研究結果顯示、當餐館獲得米其林星級時，顧客的整體情緒會下降，而其中最受影響的是服務情懷，其次是食物和情調; 但價格情緒卻有明顯的上升。這研究結果給獲得米其林星級餐館的經營者及其東主提供寶貴的啟示，讓他們了解如何為顧客創造一個可帶來正面網上評價的獨特而難忘的美食體驗。

本研究透過文本挖掘、去分析當餐館獲得米其林星級時，顧客情緒會如何改變; 透過網上餐館評論這面透視鏡子，本研究得到的結果、幫助我們確定米其林星級的聲譽所影響最大和最小的是哪些方面，以及讓我們更深入了解餐館的情調在顧客滿意程度上所扮演的角色，而這個角色在過去的研究中似被忽視。

本研究的結果提供了論據、證明由於消費者對擁有相關的認可和品質保證的這類高檔餐館一般予以較高的期望，故當他們發現期望與現實不符時，他們更容易產生負面的情緒; 因此，餐館在關注如情調方面的細節的同時，也應透過創造力和新觀念、去不斷改善他們提供的食物素質和服務水平; 而且，高檔餐館，尤其是獲得米其林星級的餐館，通常在溢價定價方面享有優勢，但當考慮到感知的奢華價值時，具競爭力的價格或會為餐館帶來反效果。

Academics and managers scour to understand which perceived quality factors are paramount to consumers during their restaurant experiences and how they influence their emotions, satisfaction, propensity to loyalty and electronic word-of-mouth (eWOM). However, previous studies are divergent regarding the impacts of satisfaction on eWOM. This survey aims to (a) investigate the impacts of perceived quality by restaurant consumers on positive emotions, negative emotions and satisfaction; (b) verify the impacts of satisfaction on the propensity to loyalty and eWOM; (c) test whether the consumers’ behavioural engagement in the SNS (CBE-SNS) moderates the relationship between satisfaction and eWOM.

This survey included 416 university students in Peru who completed an electronic form about their experiences at à la carte restaurants. PLS-SEM tested the hypothetical model based on S-O-R Theory (Mehrabian and Russell, 1974).

The perceived quality by consumers regarding their restaurant experiences positively impacts satisfaction and positive emotions and negatively affects negative emotions. Satisfaction strongly influences the propensity to loyalty but weakly the eWOM. The CBE-SNS moderates the intensity of the relationship between satisfaction and eWOM.

This study is the first to concomitantly test the relationships between perceived quality, positive and negative emotions, satisfaction, the propensity to loyalty, e-WOM and CBE-SNS. Consumer engagement moderates the relationship between satisfaction and eWOM. Accordingly, to stimulate positive eWOM, restaurants must provide their customers with experiences with high perceived quality, impacting their satisfaction, emotions and propensity for loyalty, and developing strategies to increase CBE-SNS.

Although much empirical literature confirmed the foodservice industry’s significant impact on the environment, little scholarly attention has been paid to how restaurants can improve environmental performance. This study aimed to verify the impact of restaurant environmental cognition (EC) on environmental performance through green supplier selection (GSS) and joint actions (JAs).

Using an online survey company, the questionnaire was distributed to restaurant owners/or managers who were qualified to provide accurate information regarding their operational practices. A total of 285 responses were included in the analysis. Confirmatory factor analysis was conducted to verify the validity and reliability of the measures. The SPSS PROCESS macro was used to test the hypothesized relationships.

The study showed that EC has positive and direct effects on restaurant environmental performance (REP). Each mediator of GSS and JAs played a positive mediating role between EC and REP. GSS and JAs also played multiple positive mediating roles between EC and REP. This study revealed that a path mediating between EC and REP through GSS can be used to derive the most optimal results.

This study focused on the importance of restaurant EC, which is a fundamental driver for restaurant environmental practices, but is overlooked in the relevant literature. The findings provide novel information that can be applied to operate green restaurants specifically through GSS and JAs. In particular, the present approach expands the existing knowledge on sustainable restaurant management by investigating EC from an organization perspective.

This study aims to identify the impact of affective components on behavioral intentions applying electronic word of mouth (eWOM) and is based on the “cognitive–affective–conative” model. EWOM allows researchers to get new insights about consumers’ behavior and explores new patterns of consumers’ decision-making processes.

This study is based on the theory of planned behavior (Ajzen, 1991), doubled with “cognitive–affective–conative” model (Oliver, 2014). This study applies structural topic modeling to examine the impact of satisfaction dimensions from all the Tripadvisor reviews on consumer behavioral intentions. The research sample covers all restaurants located in St. Petersburg (n = 10,424) and all consumers’ reviews (n = 286,642).

In this study, the dimensions of the affective component were identified. The results demonstrate that dimensions of the affective component (food quality, service quality, atmosphere and cost fairness) affect behavioral intention (willingness to share positive emotions). In total, 20 topics, forming these dimensions, have been indicated. Consumers tend to pay more attention toward food quality and restaurant staffs’ work when they are willing to share positive emotions and tend to point out auxiliary service when they have less willingness to share positive emotions. Random restaurant visits tend to increase the willingness to share positive emotions.

Research originality lies in a new methodological approach which is based on text mining techniques. To the best of the authors’ knowledge, this study is the first attempt to examine consumer behavior through the lens of the “cognitive–affective–conative” model based on eWOM and covers all businesses in the specific economic sphere. This has allowed the researchers to reveal new dimensions of consumer behavior and brought more insights into the consumers’ decision-making process.

The purpose of this study is to unearth antecedents of regrettable dining experiences related to the information source, action and inaction perspectives, dining companion influence and interactions among information source, the focal customer’s valence and the dining companion’s valence on regret, leading to sequential behavioral outcomes.

Using a scenario-based experimental study, 344 qualified questionnaires were collected. Univariate ANOVA and multiple linear regression analyses were implemented.

The results of this study reveal that action regret is more intense than inaction regret during the choice-making phase; dining companion negative feedback intensifies focal customer’s regret. The significance of the information source on regret disappeared when only one party reported negative feedback; conversely, when two parties in the co-consumption experience revealed negative feedback, the relationship between information source of choice and regret was sustained.

The nature of scenario-based design may lack realism. Thus, more field experiments are encouraged to test the propositions further. This research enhances our understanding of gastronomic experiences in a negative disconfirmation context, drawing upon action/inaction regret theory, attribution theory and the expectancy disconfirmation model.

From a triad relationship perspective, this study provides valuable input on who or what will be attributed to the issues when encountering a food and wine sensory failure. Additionally, insightful recommendations are supplied on avoiding the possibility of inducing the experience of regret and how practitioners can increase the potential for a memorable dining experience.

To the best of the authors’ knowledge, this is the first study that enriched the existing knowledge of regrettable dining experiences relating to information sources and social influence.

This research investigates the effects of consumers' online information searching on their dining satisfaction in upscale restaurants during the pandemic. Customers frequently rely on online sources to gather information about upscale restaurants prior to their visits.

Data from 307 diners across the top ten popular upscale restaurants in Hong Kong were analysed by using SEM to explore the links between customers' needs, information search, restaurant attributes and customer satisfaction.

This study uncovers customers' online search behaviours and identifies restaurant attributes that are associated with customer satisfaction, which were not typically emphasised before the COVID-19 pandemic. Driven by their social and psychological needs, customers devoted more time to reading written comments by other consumers compared to visual images or self-descriptions from restaurants. Only service attribute significantly influenced customer satisfaction, while food and price attributes were not significant.

The findings of this study provide valuable insights for researchers and practitioners, shedding light on the altered needs and preferences of consumers following the unprecedented health crisis.

This study contributes to the development of expectancy disconfirmation theory and needs theory through the investigation of consumers' online information searching behaviours and dining satisfaction in upscale restaurants during the pandemic. By identifying the most important attributes influencing customer satisfaction, this research can aid upscale restaurants in developing effective marketing strategies and enhancing customer experiences.

This study adopted the collaborative consumption triangle to explore the influence of online food delivery platforms (OFDP) on consumer purchase intentions. It investigates the effects of restaurants' corporate social responsibility (CSR) practices, individuals' food neophilic tendencies (FNT), and platforms' perceived benefits on purchase intention within OFDP. Furthermore, the study analyses differences in consumers' pro-environmental behaviour (PEB) on OFDP.

The 497 participants conducted a web-based self-completion survey, using structural equation modelling to analyse the path structure of consumer purchasing intention. Furthermore, differences in PEB among OFDP consumers were compared through multigroup analysis.

The findings indicate that CSR influences the perceived value of sustainability and that the perceived value of sustainability influences purchase intention. Additionally, the influence of the perceived value of sustainability on purchase intention is more pronounced among consumers with low PEB compared to those with high PEB.

The findings may not be generalisable to other countries due to cultural differences, CSR policies, and strategies for promoting sustainable development.

The study provides valuable contributions related to (1) restaurants increasing their revenue and meeting their long-term sustainable development goals; (2) providing reusable containers policy and reusable containers policy and category tags for restaurants within OFDP.

This study is a pioneering work examining factors influencing purchase intentions within OFDP from the tripartite collaborative consumption perspective post-COVID-19 and focuses on the differences in PEB concerning OFDP.

This paper aims to analyze the relationship between sustainability practices and the degree of innovation in the service provided by restaurants. The study identifies relevant restaurant segments in relation to sustainable practice-based service innovation so that effective actions to raise awareness and train managers and staff may be developed. Segmentation has been identified as a key tool when designing strategies and proposing actions. Yet, the use of segmentation techniques is still scarce regarding service innovation and sustainability in restaurants.

A segmentation analysis was carried out applying the CHAID algorithm from 300 valid questionnaires completed by restaurant owners or managers from coastal Ecuador, where tourism and gastronomy may be drivers of service innovation.

A typology of restaurants based on the sustainability-service innovation interrelation suggests three final segments: sustainable innovators focused on the value chain, moderate innovators focused on saving resources and restaurants with a low innovative profile.

The three segments derived from the analysis present differences in terms of the degree of implementation of sustainability practices, as well as in terms of the demographic profile of the restaurant manager. These segments are measurable, substantial, accessible and actionable, so that tailored initiatives to raise awareness and boost sustainability-oriented innovativeness among restaurant owners/managers may be targeted to each group of establishments.

The present research provides evidence of the positive relationship between sustainability practices and service innovation in foodservices. The segments of restaurants identified enable the design and implementation of actions that facilitate the transition of less sustainability-oriented restaurants towards more innovative and sustainable business models.
