The problem of the fourth level of Miracle Restaurant 1, the master please help

The fourth level? I've been through the customs for a long time, and I don't remember very well, but if you can't get by, try it with cheats, and if you don't want to use it, I'll give you the following advice:

1 Personnel arrangement: You don't need too many waiters, 1 foreman 1 waiter 1 waiter 2nd floor 1 waiter 1 receptionist is enough, in this way, not only will it not be crowded, but the training fee will be very small.

2. The layout of the restaurant: It should be reasonably arranged, otherwise it is easy to be blocked by customers and waiters who serve the food, which will affect the quality of service.

3 In terms of profit, look at the best-selling dishes of the season and increase the prices of the top dishes.

4 The special supplier seems to be in the column of the menu, that is, there is a picture of the dish, and then there are ingredients at the bottom, and some of the ingredients have a few stars behind them, you click on it, and the special supplier will come out.

I don't know how you choose to decorate, so it's hard to answer, but the second floor can be put less, because it's easy to get cold, and customers will complain.
