I think the determination of the theme of a food festival depends on the founder. You need to think about these questions: when and where will you hold the food festival, what food festivals will present and what styles of food will be presented. Because food culture is closely related to the content of food and the place where it is held.

since it is hosted by the students' union on campus, there are snacks from all over the country, mainly for college students, it is the campus food festival! The theme can be drawn up as "XX University X Campus Food Festival"! The subtitle can be drawn up as "Seeing China with Cuisine-Eating Cuisine from All over China and Taste the Cultures of Chinese Ethnic Groups", or it can be used as the theme, and of course, it can be interspersed with a brief introduction of the origin, characteristics and origins of various cuisines. This will not only enrich the students' lives, but also increase their knowledge and learn more about our nation and culture.
