This is my favorite Thai place in the city.
The food is absolutely unparalleled, everything I've ever ordered from the menu was top notch!
Thai Sa-On is a great place to go if you need a quick dinner before hitting up an event at the Saddledome or Corral. Everything comes out so fast (once you've decided out of the gigantic menu), and even though everything is fast you can tell it's all cooked fresh, Veggies still have texture and all the meat is not at all dry.
I heartily suggest this restaurant.
