the same idea applies to the convention-shunning sushi techniques of new york city legend naomichi yasuda. until recently, the chef partner of one of the very best, if not the best, sushi restaurant in new york. the eponymous sushi yasuda. a short while ago, under very mysterious and completely misreported circumstances, he left the manhattan restaurant which still bears his name. and at age 52, moved to tokyo to start all over again. i was determined to track him down and see what the hell he was doing. these days, this great man is running a 14-seat sushi bar in the manado district of tokyo. his wife naomi is his only helper. >> welcome to new place. thank you for coming. >> why did you do such a hard thing?
