This is a chain of dumpling restaurants specializing in the Zhong dumplings and other traditional snacks. Zhong Shui Jiao, like Long Chao Shou, turns out what taste like very mass produced versions of local food, so I've come to think of these places as the McDonald's of Sichuan cuisine.
The soup in the seafood shuijiao (海味水饺) was pretty good. The dumpling filling's texture reminded me of a low quality hot dog, however.
I also tried a bowl of san he ni (triple harmonious mud? 三合泥) It's a sweet sesame flavoured paste with crunchy and sweet toppings. This was a bit gluey, but went down fine.
The place was quite busy.
My table companions were curious about what I was eating, especially the san he ni. They turned out to be from Shanghai and spent the whole time complaining about the local food. They probably would have had a happier experience going elsewhere to eat it.
Name in Chinese: 钟水饺
