I went there once last month and it was amazing. At 6:00, I was the only one in there but the owners kept bringing me extra things that weren't included in the buffet like naan and dessert. Great food, good atmosphere, lovely people.
However, I brought a friend last week and they are under construction but still open for business. So it smells like a construction site while you are eating (though I'm sure that will be done soon) but more importantly: no more buffet. Most things on the menu are about 50 RMB, making me miss the buffet even more.
Cons: under construction, no more buffet
