Generally, like a western restaurant, the area ratio of the kitchen should at least account for 31% to 41% of the total area. Because of the variety and complicated working procedures, our Chinese restaurants will occupy a larger area and have high relative flexibility. Generally, the kitchen of moderate Chinese restaurants will account for 1/2 or even more of the total area, and it is no problem to control it at about 1/2. Of course, it refers to the situation that the size is moderate and the variety of dishes is varied. Large hotels or small restaurants choose the size according to the number and trend of dishes.
