1. Site selection, usually in a place with a large floating population, especially near the school;
2. Decoration is simple and comfortable. I have seen a barbecue shop, which is only 2 square meters, but it is very comfortable. The walls are all wooden boards, the floor is ceramic tiles, the bar, the tables and chairs are also wooden boards, and they are painted with a layer of varnish, which is the primary color of wooden boards.
3. Equipment, 2 display cabinets, one for drinks, the other for barbecue food, and multiple solid wines.
5. Publicity, preferably leaflets.
I hope it will help you.
