Las Vegas actually has a Chinatown -- a very large strip mall (naturally) on Spring Mountain Road near Wynn. There are several Asian restaurants there, but ask locals, and they will send you instead farther up Spring Mountain Road to the Cathay House (on the opposite side of the street). This only looks far from the Strip on a map; it's really about a 7-minute drive from Treasure Island.
Ordering dim sum, for those of you who haven't experienced it, is sort of like being at a Chinese sushi bar, in that you order many individual, tasty little dishes. Of course, dim sum itself is nothing like sushi. Rather, it's a range of pot stickers, pan-fried dumplings, baos (soft, doughy buns filled with such meat as barbecued pork), translucent rice noodles wrapped around shrimp, sticky rice in lotus leaves, chicken feet, and so forth. Some of it is steamed; some is fried -- for that extra-good grease! You can make your own dipping sauce by combining soy sauce, vinegar, and hot-pepper oil. The waitstaff pushes steam carts filled with little dishes; point, and they'll attempt to tell you what each one is. Better, just blindly order a bunch and dig in. Each dish ranges from approximately $1 to $3; each server makes a note of what you just received, and the total is tallied at the end. (For some reason, it almost always works out to about $9 per person.) Dim sum is usually available only until midafternoon.
The standout at the Cathay House was a vegetable bao that included Chinese glass noodles. Lightly browned and not overly doughy like many baos, it was slightly sweet and utterly delicious. The shrimp wrapped in rice noodles were big and plump, while anything that was fried was so good we decided to ignore our arteries for a while. Cathay House (which features quite a good view through the windows on one side) also has a full dinner menu, which includes the strawberry chicken invented by Chin's; it's considerably cheaper here.
