This place is really very small and intimate. Of course, I'm not sure how authentic any Thai restaurant is in the US but if this is close, it's good.
I had the fried rice and I must say it was very tasty, though a little bit dry. All my table mates seemed to be pretty happy with their meals.
Unfortunately, the server got the order wrong because she misunderstood what my friend was asking for. No big deal. There was plenty of food to go around so they didn't have to wait.
Like so many restaurants in Las Vegas now, this place is tucked inconspicuously in a strip mall. If you didn't know it was there you wouldn't know it was there.
So if small, quiet, and very intimate is your thing, with decent though not spectacular food, then Prommares is for you.
