Whatever its name, The Fish (formerly known as Blowfish) is exceptionally titillating. It’s identified on the outside solely by the abstract image of a spiny puffer fish. And on the inside, the color scheme is repeated in everything from the waitstaff’s red ties and black shirts to the black napkins and red banquettes. And the after-hours scene here is as intriguing as the original name suggested. Blowfish, or fugu in Japanese, is the most dangerous and exciting of sushi experiences. Treated improperly, the delicacy will kill you. They may not serve any fugu here, but the food is as wild as the interior design. Try a science-fiction sushi creation like the fiery Godzilla roll or the wacky but delicious cookie-crusted shrimp. The off-the-wall menu and eye-popping decor have made this Midtown sushi salon one of the hottest hangouts in the city, the place to make a bold fashion statement and do a little late-night grazing.
