It's pricey but in my opinion one of the best in Vegas for the core Korean menu. Very good meet, decent side dishes and some good soups / stews. For cheap, you can go for the all you can eat slop.
For me, Yuk Gye Jang is the most inconsistently prepared dish and I like to use it as my Korean litmus test (I use chili rellenos for Mexican). They make a spectacular Yuk Gye Jang, easily the best I've had in the U.S. and better than most of what you can get in Korea.
The Hae Mul Pa Jun was the best I've had in a decade. Most will have too much batter and turn out on the mushy side. They had the perfect balance such that there was just enough batter to hold together and cooked perfectly to provide a nice, lightly crisp texture around the fringe. A little soy sauce for dipping and BAM, you're in Hae Mul heaven.
My mother in-law ordered the Al Chi Gae and didn't like it. I take her assessments with a huge grain of salt being from Ulsan ... folks from wouldn't know good food if their lives depended on it.
