When I lived in Las Vegas I went to two places for dim sum: The first is Cathay House, which is on Spring Mountain Road, a couple of blocks west of Decatur. It's in a little shopping center and is maybe two miles west of the Strip. I forgot the name of the other place, but it's easy to find. It's in the Chinatown Mall (only Las Vegas would have a mall for a Chinatown), which also is off of Spring Mountain, maybe a mile west of the Strip. It's in the western corner of the shopping center, on the ground level, next to a Chinese bakery. Cathay House has good turnip cake, if you can get it while it's hot, and good shrimp purses. It also makes one of the few decent veggie dumplings I've had. The other place has a dish I've never seen anywhere else. It's a small pancake stuffed with a sweet orange paste. The combination of the warm, fragrant pancake and the sweet paste is exquisite. The catch is it's not always available. I would definitely ask for it. The rest of their stuff is good, better than the dim sum I've had in New York but not as good as LA or SF. Hope this helps.
