Pricey! ouch! never paid this much for the same style dishes in SF but here is vegas and it is pricey no matter what restaurants you dine on the strip hotels. I am just glad that their Chinese food is authentic! I have been here couple times over the past few years their level of service and quality of food have been consistent, will keep coming back!
