If you want to go to a very authentic snack street, it is the Gulou night market and Xisi night market.
The two are different. Gulou night market is famous, and it is usually visited by foreigners. The atmosphere is good. Several students came to Kaifeng to play, and we took them to this night market. In the evening, the snack street is very lively. Although I know those things are not clean, the things in the night market are not clean, so I want to try some. What I want is an active atmosphere.
Xisi night market, their locals say that the snacks in this night market are delicious and cheap.
But after both of them have been there, I think the Drum Tower is better, because it is lively and fun, and Xisi Night Market is not so lively and cheap.
I am in the new campus, and take a taxi to Gulou Night Market 1 1 yuan or so. The old campus seems to be close to the Gulou night market. I'm a road idiot. I've only been in Kaifeng for one year, so I usually take a taxi after school in Kaifeng, and I can't remember the way.
Hehe, I'm a little wordy. Give an answer for the first time. Hehe ~ I hope it helps you.
