I lived in Bangkok for 4 years. My wife is Thai. We both agree that this place is the most legit Thai food we have had in Phoenix and possibly State side.
The poor review by Phil N. that states you cannot choose your heat level is not correct. We order extra hot for us and no spice for our children. Real Thai places don't have a 1-10 scale. Just let them know how you prefer it and it will be done. Also, what Phil N calls "some old guy" is the owner and chef and he personally handles all orders. It's hard to find service like that these days.
