I have a 5 course meal there, and the service was good, but slow. Food was quite good.
Good stuff: Mutton, chicken dishes, a chicken appetizer, Jasmine tea, very good chicken soup. Shezwan chicken was my favorite.
Average: Rice, noodles. Mushroom and cheese dumplings( but try it, for a different experience.)
Some of the dishes really felt authentic, and better than Mainland China franchises that I have been to.
It was expensive, but since I went with a group, I don’t know the full price.
For a once-in-a-while experience, go for it.
