This buffet is like the culture about"north side of China" ,food may have little bit spicy , if you really can not eat spicy food, just leave this restaurant away.
The dumpling may taste 90% same, but if you are the one who really know about dumpling(know how to make it tasty, Know how to cook, etc), you may satisfaction with their dumpling?very traditional taste of " northern area's culture of Chinese dumpling(?????", if you are not the Chinese people, the place may not be a good choice for you.
