Perceived authenticity in ethnic and cultural restaurants: a systematic review and meta-analysis

Purpose This study aims to address fragmented evidence on perceived authenticity in restaurant contexts by developing an integrated understanding of its key antecedents and customer outcomes in ethnic and cultural dining settings. Design/methodology/approach A systematic literature review identified 100 studies, with 50 meeting the inclusion criteria for meta-analytic synthesis. Effect sizes were synthesized using random-effects models, and moderator analyses were performed to examine the roles of culture, age and gender. Findings Perceived authenticity is strongly shaped by tangible cues, particularly brand image and food quality. In turn, authenticity exerts robust positive effects on customer satisfaction, revisit intention and word of mouth. Moderator analyses further show that individualism strengthens the authenticity–positive emotion relationship, that older consumers place greater emphasis on authenticity in forming memorable dining experiences and that female customers are more sensitive to interpersonal cues. Practical implications The findings provide guidance for restaurant managers on developing and communicating authentic dining experiences in ways that support favorable customer responses. They also highlight the value of considering cultural and demographic differences when designing and delivering authenticity-related experiences. Originality/value This study clarifies how key antecedents differentially shape perceived authenticity and how authenticity influences customer outcomes. It also identifies boundary conditions across cultural and demographic contexts.
