There is a great white shark in the west gate of the National People's Congress (or a big shark? ), seems to be quite famous, like a 49-person, buffet hot pot, including drinks, affordable should be no problem, the taste should be ok, the scene must be "warm" ...

There is a "small fishing village" not far from Ximen (on the way to Xiaonanzhuang), which is also a small hot pot restaurant. The taste is OK, but it is not too expensive. You can try it.

Other serious hotpot restaurants may be Jinshan City.
