Let me introduce you to the general distribution of Kunming’s food.
If you want to eat everything in one street, it's impossible.
Xiangyun Food City in Kunming Nanping Pedestrian Street has a lot of things, but the taste and price are not very good.
I suggest you don't go.
There is a snack bar next to Nanping Street called "Yunping Snacks".
There are many things inside, including cans of stinky tofu rice noodles, braised noodles, and roasted tofu, all of which are quite authentic.
You'll know as soon as you get to Nanping Street and ask.
The next step is to go to Wenlin Street to eat at the time-honored "Duanshi Small Pot Braised Bait Silk". That shop has a long history and the taste is quite good.
