First I will say, this is a nice atmosphere and the food was fine. But for the price, the portion size, the $2 upcharge for brown rice (on top of the price for the lunch) and the very slow service at lunch, this is what brings me to the lower rating.
I've been to other Thai places here in the Valley, that the food has a little more flavor, the portions are better, the service faster, and no additional charges for a different kind of rice.
Give it a try, but don't expect a lot.
