This place is pretty good for what it is: strip mall Thai food. I've been here a few times and sampled their Thai salad in addition to their pad Thai. The Thai Salad is bland and like something you could get from Panera, the pieces of chow mein noodles made it taste inauthentic to me. I've had authentic Thai salads many times before, and the balance of sour-spicy-sweet is just not present in this salad.
However, the pad Thai is a good gauge for a Thai restaurant, and the pad Thai here was pretty good and the spice level was definitely on point. Unlike some places, Thai Foon will bring the heat if you ask for it, and for that they get 4 stars.
