We dined at this restaurant which is located in the Rio. Poor experience! The service was very poor and not much better than the food. Few, if any, of the wait staff could speak English and they appear to cater to mostly Chinese tourists. Had difficulty getting our water glasses refilled. My wife requested another bowl of rice, but it took them 10 minutes to deliver it. We requested a second dish of an item and after 10 minutes, they finally told us they ran out and had to cook some more -- we cancelled and left. Servers came by with carts twice, then we could never get them to come by again--worst Dim Sum ever!
