This is the best Korean restaurant I've been to in the states. They are definitely the most authentic Korean I've had here, not only the food, but also the service as well. Don't come here expecting to be treated like you do in typical restaurants. They aren't going to annoyingly come by every two minutes asking how the food is, do you need anything, etc. They will give you prompt service, helping you cook the meat and refill your drinks.
The food is outstanding. All different meats have great flavor. The side dishes are decent. I try and visit at least once every time I come to Vegas.
