My wife and I went to this restaurant based on recommendations from friends, and it was excellent. We went around 9pm, and had a chance to talk with the owner in Mandarin.
The food was authentic and executed at a very high level. On point with the flavours, mouth feel and the overall composition of the dishes. They make authentic Chinese Northeastern food, and the chef owner is an experienced chef.
The restaurant is very clean.
Would highly recommend that you give it a try!
