This was quite possibly the best meal I ate while in Vegas; it was definitely the most bang for my buck. I went with a group of 6 people. Two of the members of our party were locals, and they were smart enough to call ahead and make a reservation -- this place is pretty small.
I was not disappointed with the food. I ordered a Thai tea and it was surprisingly big for $3. The shaved ice in it was different than what I am used to, but I liked it. I ordered the spicy eggplant. The server asked how spicy we wanted our dishes on a scale of 1 to 10; she warned us that 4 is approaching "the danger zone". I have been to Thai places that overestimate their spiciness, so I went with a 6. It was pretty damn spicy, but delicious. I wish I could have taken home my leftovers because I couldn't eat it all!
I will definitely make my way back here next time I'm in Las Vegas -- since it's off the strip it's very lowkey and service was great.
