It's not too shabby for a small secluded Japanese restaurant owned by Koreans. The menu offers a mic of Japanese and Korean style basic food..
Means the bento box, sushi, sashimi, spicy chicken, bulgogi
One of the most try if you're a sashimi fan is chirashi which is sashimi on a bed of rice. They have the lunch portion which is smaller than the dinner portion. Like how they have this, offers a size variation which is awesome.
Price wise is somewhat reasonable for a downtown sushi place offering decent sized portion.
Location, just right of the Sherbourne subway. Beware as when lunch hour hits, excited longer line. Even weekday dinner time, it's continuously flowing with people.
