This is a very nice family run place immediately next to the much beloved Phat Phrank's. The restaurant is small with maybe seating for about 20 but comfortable and inviting. In particular we really enjoyed the soft shell crab salad and the Tom Kha Gai (chicken and coconut milk soup). Generally, a thing to watch out for here is that their idea of spiciness is set a little higher than most places. So, if you normally like your Thai food a 4 out of 5 for spiciness, you should start with a 3 out of 5 here. (Or maybe even a 2, if you want to be cautious.) In terms of prices, I was pleasantly surprised. My impression is that the Sin City Thai prices run about 15% lower than those of competing Thai restaurants. One more cool thing about this place is that if you're dining out with friends and maybe one part of the group wants Thai and another would prefer Mexican, both Sin City Thai and Phat Phrank's are totally cool with you getting food from both places and eating in either. (They're not related businesses, they're just both very up with customer service about things.)
