My Korean-savvy informant tells me this place is Korean-managed, but they definitely play up the Japanese angle more than most other Japanese restaurants in the area. In addition to the usual suspects, for example, the sushi bar offers “Japanese” mackerel, “Japanese” snapper, etc. They run some mildly exotic specials: spotted sardines were excellent, but wasabi-marinated octopus tasted like bait (and not of the fresh variety).
Their kitchen also does good work: deep fried miniature octopuses are nice, as is the unagi don.
