This is a pretty mixed one,
The ambience, the atmosphere and the service was excellent, the restraurant looked fancy outside but their cost is pretty cheap compared to other restaurants in Vegas.
The food however is not that good and doesn't met my expectation. Tried the basil chicken and it was meh, as a Southeast Asian and a frequent consumer of Thai food I'm sure that this is not authentic.
The tom yum is acceptable but that's just it.
If you just want to eat to fill your belly and eat Asian food then you can eat there but if you are genuinely looking for Thai then this is not for you.
