Now there are quite a few Korean spots near the strip. My recommendation? Try elsewhere first.
What we ordered:
Dolsot Bibimbop
Naengmyun
Kalbi Tang
Dok Mandu Guk
Ojingo Bokum
Service was a-ok. Not great, but not bad. The food was ok. Not great (or even exceptionally good), but not bad. Everything was just ok.
Expect to pay more because you are in Vegas. But price didn't hurt the rating.
It's just that there was nothing that great about the food, and there are other choices to try.
