The bottom line: Just off the strip, almost at walking distance (unpleasant walking, that is...) is this small hole-in-the-wall shop that surprised us with authentic, friendly, tasty Thai food.
The Pros: The food was as original as I remembered it from Thailand. The service was friendly and authentic. The place was packed with locals (as oppsed to us tourists). The price was more than fair.
The Cons: The location is a bit off the beaten path.
