Have just moved here from the UK and am on a sushi grade tuna hunt. We were lucky in London to have a great Japanese market nearby that had quality sushi grade fish and am really hoping to find something similar near the Madison area if I can. I've heard about Mitsuwa and intend to check it out but was hoping for something a bit closer so that I can make sushi often. Does anyone have any recommendations? I did try Kam Man in East Hanover and although the tuna wasn't awful, I really wasn't thrilled with the cleanliness of the fish counter. Thanks!
