This place may look ordinary inside, but the food and owner are far above that. The food was really good, and the owner who served us was one of the most enthusiastic restaurateurs I've ever seen. He kept bringing us more food to sample as the night progressed and made sure we didn't leave hungry. As for my entree, the chicken katsu, it was nothing short of great. The Korean fusion menu here works well.
It's good to go off the strip when visiting Las Vegas, because otherwise you will never find hidden gems like this one. Jackpot!
