first of all, I didn't understand what you asked, and my department understood it too well.

I will share with you my own experience:

Now, according to the number of self-service consumption, the three grades of high school, low school and low school are also set according to different groups of people. Recommend a mid-range one, which is acceptable to most people.

according to the types of products, it can be divided into: barbecue buffet, hot pot buffet, Chinese buffet, western buffet and the combination of Chinese and western food. The profit of barbecue is low, and the hot pot is better. I recommend that you have a wider range of Chinese and western food consumers, from junior high school students to 35-year-old main consumers.

The main sites are shopping malls, dining streets and residential areas; For areas where government departments enforce the law strictly, it is strongly recommended that you do shop-in-shop in shopping malls, which will save a lot of things and have potential customers.

contact me if you need any help.
