Probably the best overall Chinese restaurant in Vegas, Asian BBQ and Noodle is a casual sit down place with roast duck, BBQ and crispy pork, and many other options.
I will say this place is unfriendly towards non-Chinese speakers who aren't familiar with this style of restaurant. They aren't mean but the menu is too vague and many of the waiters and waitresses speak much English. It is also cash only.
Still, the food is excellent and the prices low. My favorite is the cha siu. I get it either with rice or in soup with noodles.
