I been looking for a great XLB place in Las Vegas. China Mama was recommended by a girl friend. We came here during lunch time, and it was quite empty. But still hard to find parking, because of all the surrounding restaurants in the plaza. We just ordered the XLB, beef roll, fried onion pancake, and tan tan mien. All the food was delicious, but nothing too crazy about. It will do my XLB fix. Prices are kind of steep for chinatown. I would of gave them four stars, but their service is not welcoming at all.
