Nice and clean place, perfect for date night. The waitresses are always friendly, but service can be a little slow when it gets busy. That probably has a lot to do with the fact that I've never seen more than one waitress at a time.
They have a beautiful full bar and a good selection of cocktails and beers. No sushi, which is a shame since the sushi bar looks really nice.
I come for the Soon Tofu stew, which is always really good, but very mild. Ask them to make it extra spicy to get a more flavorful stew.
The banchan is pretty good too. I haven't tried the barbeque, but I've seen others ordering it, and they look like huge portions.
In short, good Korean food, probably your only option in the Summerlin area. Try if you're on this side of town!
