The following types of shops may be lacking in the food market:

1. Specialty snack bars: There are usually many snack bars in the food market, but there are few specialty snack bars. If you can open a snack bar with local characteristics and provide local unique food, I believe it will be very attractive.

2. Fast food restaurant: Although there are various snack bars in the food market, there are not many shops specializing in fast food. Fast food restaurants can provide convenient and fast catering services to meet the needs of busy urbanites.

3. Breakfast shop: Many people are pressed for time in the morning and may not have time to cook breakfast at home. It is also a good choice to open a breakfast shop near the food market and provide various nutritious breakfasts.

4. Fruit shop: There are usually many fruit stalls in the food market, but there are not many special fruit shops. If you can open a fruit shop, provide fresh fruit and excellent customer service, I believe it will be welcomed by many people.

5. Green food store: As people pay more attention to healthy eating, opening a store specializing in selling green food will also have a good market. These foods include organic vegetables, fruits and grains.
