North Brooklynites don’t have to wander the odorous (to put it lightly) Chinatown labyrinth to get a fresh fish fix, anymore. Elegantly displayed ocean fare is displayed without labels at Williamburg’s Osakana, but that’s the point: the staff want customers to ask questions and engage, also offering classes in how to handle Japanese knives and methods of fish preparation. Think of it like a seafood seminar, but the only cramming you have to do involves fitting as much shrimp into your mouth as possible. Owner Yuji Haraguchi, who helms Okonomi sushi restaurant in the neighborhood, started the venture to satisfy his customers' curiosity about the source of their sashimi. The name translates to “honor your fish,” and they do, hand-selecting the most attractive salmon, fluke, swordfish and more at Fulton Fish Market daily.
