The only way to change this situation is: 1. You can't cover everything. Guests can eat whatever they want. Otherwise, it will increase the purchase cost, and secondly, it can't guarantee that all the dishes ordered by the guests have raw materials.

2. Make your own menu and standard menu (this standard menu is not for guests, but for chefs, who are required to strictly control the ingredients and preparation methods of the dishes according to the requirements of the menu, so as to "keep the taste unchanged"), and then engage in some promotional activities according to the dishes on the menu (for example, what dishes are not selling well in recent days, then give some discounts to the guests), or introduce this dish to customers when ordering.

People who order food must be familiar with all the dishes on the menu, including taste, weight and preparation method.

4. You can replace the unsalable dishes every once in a while, and then replace them with newly developed dishes or seasonal dishes, but you must remember that "it's better to be short than excessive", and the dishes you want to serve must be accessible.
