I think this place is trying to make itself seem 'popular' or attract tourists (especially from Asia) by relying on the fact that many celebrities (including Korean-Japanese UFC fighter Sung Hoon Chu or Yoshihiro Akiyama) came to eat here during their stay in Vegas.
You can see that from the many pictures of the owner with the celebrities posted on the wall of the restaurant. The pictures can get annoying are there are just too many pictures it can really drive you crazy. Restaurant itself is ok, there's not really a "vibe" of either a Korean or Japanese restaurant, more like something in between.
Food is average. My Agu-jjim (braised spicy angler fish) didn't have much meat in them and Ganjang-gyejang (Soy sauce Crab) was wayy too salty. Their Galbi is pretty good but small and overpriced. Not really my type of place, we just came here because of our Fob manager who wanted to eat "Korean" food every day during our stay in Vegas...*sighs*
