The purpose of this study was to explore the roles of authenticity (food authenticity and atmosphere authenticity) and nostalgia in tourist’ food experiences. Data were collected with tourists visiting a local food night market in Macao. CFA and SEM were used for data analysis. Results suggested that authenticity, especially atmosphere authenticity, has a positive influence on nostalgia, which in turn influences attitude towards local food, perceived gastronomy destination image, as well as revisit intention for food consumption. The findings also provide some practical implications for the food night market as well as DMOs.
