As Korean people who tried a few Korean restaurants in Las Vegas, we thought it was the best soon dubu here. Restaurant seemed clean. We did not eat the Korean BBQ (we honestly try to get away from it). Even though it wasn't on the menu, we had bibim neng myun and it was delicious and refreshing during the hot day! Kkakdugi was fresh as well. I would go back.
(This was a recommendation from the owner of the Korean bakery we went to earlier in the day. She had felt it was the most authentic food in Vegas)
