This is a small restaurant that is next to some construction, so it is really easy to over look (as I have until this last Friday), and it is a nice little gem.  I first had Thai at a little, very authenic place in Evanston IL by the Northwestern campus, it is has ruined me for many Thai varients that i have tried over the years here in AZ (Thaifoon comes to mind as the worst mistake with the most development dollars invested...).  I tried the chicken green curry, the spice beef hoisin stir fry, and the shrimp garlic noodle: the best by far was the green curry, which was ordered spicey: it did have some kick in the aftertaste, but will be definitely ordered extra spicey in the future.  Very reasonable prices, and you could tell that they do a lot of lunch and take out business, but every single table was filled (the whole place probably seats 40 or so).  GIve it a shot, especially the curries.
