let me talk about Suzhou. The most prosperous areas in Suzhou are Guanqian Street and Shilu Road, both of which are commercial pedestrian streets. Usually, there are many people, and it is simply a sea of people when it comes to weekend holidays. But it seems that the catering industry here is saturated, and there are all kinds of restaurants of all grades. You can go and have a look. If your store is distinctive enough, customers are absolutely indispensable. There are many cars to Guanqian Street, more than half of them arrive from the railway station, and there are also many cars to Shilu.
In addition, there are many neighborhood centers in Suzhou Park, which is a new urban complex. There will be many people going for dinner at weekends, so you can also consider it.
good luck!
