I've been to a few Thai restaurants in Vegas (yeah even Lotus of Siam... Which has great food but the ambiance of a bus depot)... This is hands down our favorite Thai restaurant.
Nice ambiance, great pricing, and the dishes are amazing. I usually stick to the Crab Wantons and Pad Thai but they have a new tapas menu that is insane. Everything we tried was a winner.
Hidden Thai jewel in the southwest. I promise you.
