Analysis of the composition of your business district, the composition of the business district determines your consumer groups:
Sell refrigerators electric car furniture and so on merchants, usually business is not very busy. Such merchants if the mall allows, usually at noon to cook their own meals. In the evening go home for dinner. The mall is not allowed to open fire, a lot of people are with meals or call their own takeout, takeout is not too expensive, usually about 10 yuan to get a meal. The first thing you need to do is to get your hands on some of the most popular products in the world.
It is recommended that you go to these malls at lunchtime to see for yourself. Ask some random merchants what they eat at lunch. After lunch, look at the mall's trash can is probably what kind of garbage, so you know very well the merchants' lunch habits, spending power.
I personally recommend doing mobile fast food trucks. Burn 6-8 dishes in one meal. Insulated bucket of rice. 8-12 yuan a fast food is more suitable, so less investment. The cost is also small, not recommended to open a physical store.
