First of all, I want to say that there are many tea shops and few ice cream shops in the university town. It is said that the ice cream shop may develop to some extent, but it will not be very good. First, ice cream is not as seasonal as milk tea, and students have to take three months off. Do you think that when it is ice cream season (July and August), students have a holiday?
Barbecue may be a good choice. Now there are many barbecue shops in the university town, and the business is very good.
I have an idea. You can rent a smaller facade and combine barbecue and ice cream to make a take-away form. Barbecue can be made into smokeless barbecue. This may be good for me.
