not sure if this is the same mike, but the chef at sushi tanoshii on clark goes by the name sushi mike. according to metromix he is the former chef of hama matsu. I don't know where else he may have worked before that. (i.e. SUSHI) we ate there a few weeks ago and it was pretty good. however, i don't know too much about sushi though so i couldn't begin to compare it to other places in the city
