if you have a car and you're willing to drive FOREVER, oishii in sudbury (which is, yes, kind of far >.< ) has the best sushi ever ever. however, it's a. in SUDBURY, and b. not exactly cheap. (probably about average price for really good suburban sushi, tho.) it's so, so good.

but if you don't want to drive to sudbury (and really, who could blame you), bluefin is yummy. and i second shino express.
