the ratio of western restaurant area to kitchen area is 7:3. The ratio of Chinese restaurant area to kitchen area is 3:1. The area of kitchen should have a proper proportion in the area of restaurants. Kitchen area is very important for production, which affects work efficiency and quality. If the area is too small, it will make the kitchen crowded and stuffy, which will not only affect the working speed, but also affect the working mood of employees; If the area is too large, the walking distance of employees will increase, which will not only waste time and energy, but also increase the cost of cleaning, lighting and maintenance.
