You can make money by increasing your attributes to 100.

The legendary Yakitori starts off as a fast food, with the first three dishes being rice, toast and grilled chicken. Then set the menu to only grilled chicken and save it. Then you wait for the housewife to come in and eat the roasted chicken. When she finishes eating the roasted chicken, there is a chance that she will give you a dish called roasted chicken. If it is not delivered, you will continue to wait until she does. Then I set the menu to only have roasted chicken, and then use two pesticide-free rice to fortify the roasted chicken. The unit price can be negotiated to 7,500. This is the perfect start. The same goes for later. You only have the most expensive dishes on your menu, so every customer who comes must order your most expensive dishes. That is to put only one dish on the menu, the most expensive dish, and then work hard to improve the attributes of this dish. Among the attributes of a dish, there are __え and カリスマ性, which are related to the price of the dish. If you only need to increase the price, just increase these two attributes to 100.
