I am from Jinzhou, and the most famous feature of Jinzhou is barbecue.
Many of them are distinctive, such as some chicken feet and some chicken heads.
I can't tell you this detailed address. Basically, there are barbecue shops everywhere you pass by, and they all taste the same.
The smaller the general store, the better the taste.
Then there are Jinzhou dishes. This is kimchi. If you buy this, you can find a supermarket to sell it1around 0 yuan.
The rest are snacks. There are many snacks in the night market now, but they are basically the same as those in other cities, and there is nothing too special.
Jinzhou also has good tourist attractions, Bijia Mountain and Beiputuo Mountain. If you haven't been there, you can go and see them.
hope this helps
