In Short: Selection is average, the taste could be better. Try the hot pot on the weekend, probably the best thing there.
The best thing about it is the spacious atmosphere, where you are not packed in like sardines. The selection is about average to any other buffet. You can find the typical chinese selections, some sushi, and dessert. Only thing is that it's all oily and salty, flavor of the ingredients are lost in thick sauces. It's fairly cheap so if you just want to stuff your stomach with random food, it's perfectly fine.
One thing that does set this place apart is the ho pot. I think it's only available on the weekends but I maybe wrong. They provide you with a burner and either spicy or mild flavored stew. Then you can pick your veggies and meats, then have at it.
