First, meet the most basic needs of customers. 1, health; 2, taste; 3. Environment; 4. popularity. The first three items are indispensable, but it doesn't mean that you should make a five-star standard, but you should do your best within a few blocks at least. As for popularity, you need some strategies, but try to avoid attracting customers at low prices, otherwise everyone will not make a profit in the end. For example, ask some friends to help you support the scene. Most people pay great attention to popularity when choosing a dining place, because they think that a crowded shop means being recognized. As you said, the food you cook tastes ok, so fill your food stall with your own people first, and your popularity will gradually come up after a while.
Second, special dishes, launch a special dish every day, post it with big posters, and attract customers through disguised promotion.
Third, pay attention to entertainment. Eating food stalls is not simply for eating. Doing something entertaining around you, such as a big projection screen and a colored light area, will also bring you many customers, but don't engage in karaoke.
The last sentence: if you want to do business, you will get it if you give up.
