As someone of Chinese origin, I can say with 100% certainty that the selection of authentic Chinese restaurants are extremely limited in Las Vegas...especially ones that specialize in noodles. Most Chinese restaurants here in Las Vegas caters more to an American palate. And of the authentic Chinese restaurants, most are just "meh."
And that's why i was so excited when I saw Mian while driving down Spring Mountain, and I was not disappointed when I finally went. The noodles were delicious AND very spicy...as Sichuan-style Chinese food should be.
The service was also fast and attentive...an unusual quality for an authentic Chinese restaurant in Chinatown ;)
I also love the ambiance of the restaurant...very trendy. Mian somehow made a very boring, traditional type of Chinese food feel "cool." The ambiance of the restaurant makes you want stay awhile after you finish eating to hang out with your friends and chat.
But yea, great restaurant. Definitely would come back. A must go-to place whenever you have friends from Taiwan or China visit.
