Under normal circumstances, the school canteen building will not be built too high, and the canteen will not exceed the third floor. The purpose is to make it more convenient for teachers and students to eat, not too tired, and also to facilitate the logistics configuration of the kitchen. And it is not suitable for building high-rise buildings, because it covers a large area and costs a lot. The meals in school canteens have certain local characteristics, and more and more attention is paid to the management and sales of national classification windows, and to the eating habits and tastes of teachers and students.

Generally, school canteens are rich in dishes. According to the scale and object of dining, there are at least a dozen to hundreds of dishes. Even so, it may not meet the personal taste needs of every teacher and student.
