Let me preface this by saying that I've tried many of the fine Chinese restaurants around Vegas. This was the first time I've encountered "wandering waiters" who disappear for 15-20 mins at a time. So, VERY poor service.
As for the food...the beef noodle soup was almost inedible. The Shui Mai was average, but in its favor, the shrimp was fresh. The BBQ pork bao was overly sweet, but okay. The xiao long bao (regular) had excellent flavor, but the skin was thick and tough.
Might have been 3 stars without the poor service.
