Came here after First Friday late at night and even though they were closing, they were gracious enough to let us order. Yes, we were "those people." Ocha has been in Vegas for decades and is my family's choice for Thai. My Thai friend whom I was with also frequents this place with her family, so I know it's legit. We ordered about 6 dishes, and for the price it was a bargain!
The service was prompt, and they do a good job of accurately spicing the dishes based on what you tell them. Most Thai restaurants always over do it in my opinion, even after you tell them you're a weenie when it comes to heat. Pad see ew is my staple dish, and it never disappoints. Strongly suggest coming here if you're in the mood!
