Baesusa serves Japanese-style sashimi and grilled dishes in the alleys of Ikseon-dong. Octopus karaage, grilled blackthroat seaperch, and clams steamed in liquor are listed as its representative items, and the sashimi is served aged. The antique interior is on the dark side, only sake, wine, and spirits can be ordered, and some menu items run out of ingredients early. The hall is cramped, so a wait is unavoidable.
