The old canteens in colleges and universities have been set up for some of the uncertainties in the fire evacuation performance due to the stagnant construction of buildings and the concentration of combustible materials. In order to study the evacuation performance of the old cafeteria in colleges and universities, the fuzzy evaluation method is introduced to evaluate the fire evacuation performance of college cafeteria，and an old canteen in an university is used as research object. The results show that there are some problems in the evacuation channel width and evacuation management, and in order to improve the performance of the canteen fire evacuation the paper has proposed feasible rectification suggestions.
