One might think, with a wacky name and being located in a casino, that Ping Pang Pong isn't going to be any good. However, it's definitely one of the better places in town (and my favorite) for dim sum. The restaurant is little bit small, so expect a bit of a wait on crowded days. If you don't see a dish that you want being carted around, you can ask and they will generally make it for you. Prices are a little bit more expensive than the other places in town, but not that much (maybe 50 cents to a dollar more per dish).
Also, I saw Johnny Chan eating here once. If Ping Pang Pong is good enough for Johnny Chan, it's good enough for me, and probably you, too!
