How to price a dish when opening a restaurant? Tell me in detail.

The menu price positioning of catering industry is related to the store rent, the number of waiters, the market price of dishes and the cost pricing of seasonings. For example, a simple fried lettuce is located between 18 yuan and 25 yuan, and each batch has different sales ability and different value. Take 18 yuan as an example, the market will use 1 yuan to buy a catty of lettuce and seasoning, and the rent will be added with 2 yuan. Kitchen chef 2 yuan (salary), waiter 1 yuan (salary), water and electricity fee 1 (yuan), cleaning fee 1 yuan, then the cost price of this lettuce will reach 1 1 yuan, and the remaining 7 yuan will get a net profit with tax and tool wear.
