I have to agree with Steve L in that the Mongolian beef I had was not what I usually get with Mongolian beef. It WAS really good, though, so I can forgive them the fact that it isn't really Mongolian beef. (Not even remotely spicy at all).
My sister got the chicken with the noodles... I can't remember what that is called. She liked it a lot. I took a bite of chicken and did not enjoy it, but it wasn't my meal.
It seemed rather reasonably priced to me, probably roughly what I would spend per person at a place like PF Changs, but for better food in my opinion.
It is entirely possible I didn't notice, but I think they did not charge us for refills. I also agree with Doreen B. It is nice that the restaurant is really rather quiet despite facing into the casino. I also liked that it is a no-smoking restaurant.
