After seeing one too many news stories about overfishing and the crashing tuna population, my wife and I are trying to be better about only eating sustainably-caught fish. I can do fine when cooking at home - they sell pole-caught tuna and swordfish and farmed shrimp at Fairway, which is about all I cook - but sushi is harder, and is something I can't live without. Does anyone know of any sushi places that serve sustainably-caught fish? I'm in southern Park Slope and would guess that my delivery standby Kiku doesn't qualify; I'd love to find a nearby option (we've traditionally ordered takeout sushi at least once a week) but would be happy to hop into a car (or subway car) and travel for someplace that made me feel less bad about myself.
Unfortunately I posted this on the Manhattan board earlier, looking for more high-end places for my occasional Manhattan sushi splurges, but no suggestions yet. Hoping that the socially conscious Slopers may have some ideas.
