I've been using yelp for years, but finally had to write my review because of how shocked I was that this place was not more busy. I was introduced to Thai Ploy about a month ago, and I've been back once a week since. I've yet to find a dish there that I don't like (including tasting my friends'), but I especially like the Massaman Curry and Pad Thai. This has become my favorite Thai place in AZ, and I drive past several others to get there. Check it out and you won't be disappointed!
