Yes / This study addresses a lack of research on the effects of consumer brand authenticity, brand image, and age, on brand loyalty in time-honored restaurants. Time-honored restaurants are long-established and well-recognized traditional restaurants that offer local or national foods and culinary culture. Empirical data were collected from 437 respondents in Beijing, China. Structural equation modeling (SEM) was used to ascertain relationships between variables, and fuzzy-set qualitative comparative analysis (fsQCA) validated the SEM results. The three brand authenticity dimensions were found to have differing effects on brand image and loyalty. True-to-fact authenticity had a significant effect on true-to-self authenticity, while true-to-ideal authenticity had a significant effect on brand image. True-to-self authenticity affects brand loyalty directly and indirectly through brand image. Some of the relationships were also moderated by consumer age. The results uncover the complexity inherent to consumer brand authenticity evaluations. They have implications for time-honored restaurants’ marketing and brand positioning strategies.
