We had lunch here yesterday. The service and food was great. Very authentic Cantonese food. I didn't expect a good dim sum restaurant inside a Las Vegas casino. It is a gem despite its undignified name. Apparently it is not a hidden gem either because there was a long line outside the restaurant before noon. Don't empty your wallet while waiting in a field of slot machines, save some to pay for the lunch. Its Chinese name is Jin Yuan Bao (lit. gold ingots) which is a much better name especially to those high rollers in Vegas.
It is actually much better than the dim sum restaurant in Las Vegas Chinatown on Spring Mountain Road.
