A second offering from the owners of Brookline's organic sushi specialists, GY (which means "health and energy") peddles fresh, all-natural raw fish in a pastel green/teal-painted 40-seat spot boasting a wall of seed-filled jars, giant hardcover picture book menus, and a front-window-blocking forest of bamboo designed to be calming/up the number of panda walk-ins. Specialty maki rolls include the lightly fried Delicious rolled w/ tuna, salmon, and asparagus; a massive Grilled Seafood Deluxe (shrimp tempura maki w/ baked scallops, shrimp, crab, and flying fish roe); and a spicy mayo-topped crab roll w/ avocado, cucumber, and tempura flakes called the Sunny, which tastes even better when you Cher. There's also other healthy deliciousness like the cream cheese'd Fashion packed w/ fresh water eel, cucumber, and avocado; the Hawaii (sweet potato, mango, and banana with multi-grain rice); and the spicy crab, banana, and eel-filled Doomsday which features three types of flying fish roe -- so good you'll have no choice but to Superman that roe.
If you prefer your grub cooked, GY also rocks apps and Japanese entrees like lightly breaded and deep-fried salmon katsu w/ rice and miso soup; pan seared pork ravioli; and a Beef Tataki with a sauce of spicy ponzu, which can also be a surefire route to success, if you change one vowel, and get fat off of other people's dollars.
