The place was cute (I can't comment on authenticity, because I'm as white as they come) and the strip mall was a typical strip mall, not intimidating whatsoever.
The food was satisfactory. My friend and I had crispy tofu to start, I had the Hot and Spicy noodles with tofu and my friend had the Ginger Tofu. We were both incredibly happy with the way the tofu was cooked - it was ACTUALLY crispy - but just thought the sauces and veggies were "meh."
I would be willing to try here again for one of their curries. I'm not sure when I will make it back to Siam Thai; the distance is a little to far to drive for a mediocre meal.
