If you love Chinese dumplings filled with pork or chicken and vegetables, you have to try Champion Gourmet on Spring Mountain at Decatur, 2nd floor of shopping center above SF Supermarket. (5115 Spring Mountain Rd Las Vegas, NV 89146-8717 (702) 388-1168) If your mom made dumplings, these will rival them. My husband is Taiwanese, and his mom makes incredible homemade dumplings, and even he sometimes slips and says that Champion's are better.... whoops!
They also have the best Taiwanese-style shaved ice desert in town-- a pile of shaved ice topped with delicious things. Of course, my favorite is the red bean, but you should just ask for everything, determine your favorite, and then you can custom order next time.
Lots of people go there to eat shabu shabu, so if that is your thing you can try it too. And, you can buy the best Chinese-style beef jerky by the pound there as well.
The owner is super nice, and all of the staff is helpful if you don't speak Chinese.
It is definitely one of the local places that I don't want to see go away, so eat some dumplings.
