Personally, I suggest not to open a billiard hall on the first floor. If it's a high-end billiards club, it can't be opened on the first floor, because it needs a comfortable environment and people are rude at any time.

If the billiards hall has been opened on the first floor, it is suggested to open a bar, tea bar or internet cafe on the second floor, but the internet cafe with billiards is not of high grade. If you are tired of playing billiards on the first floor, you can rest and have tea on the second floor. There are many people in the bustling area, so there are many people who need leisure and entertainment.

Personally, I think the best match is:

First floor: the facade is rented directly. Busy areas are often sold on the first floor for daily use, such as catering, clothing, supermarkets and the like. If you have enough financial strength, you can do the same.

Second floor: leisure bar+billiards club. The place is big enough to be separated by hollowed-out ornaments. At the same time of rest and entertainment, a comfortable and elegant environment is more attractive.
