The atmosphere was the highlight of this place. The place has a woodsy feel, the dishes and cutlery are rustic, and, like many have noted, the music was ambient. However, I was surprised to find the service inattentive - especially considering that the place was barely 50% full.
I got the hot beef noodles - it was okay but far from mindblowing. Also, for a Korean restaurant, there is a surprising lack of "banchan": one dish of kimchi. All in all, I'm confused at the 4 star rating.
