I was introduced to this place as a Korean restaurant, so I usually order something Korean such as one of the bentos: Bulgogi, spicy pork or Kalbi with salads. I like these three a lot. The salad is usually romaine hearts with sesame paste based sauce. The portion of a bento is more than enough for me even when I'm hungry. I tried the beef soup once and it was good too.
My friend ordered sushi and shared with me. It's rolled sushi with sashimi on top, which I like better than nigiri.
They don't have much of sitting space, but I never had problems finding seats on the second floor.
