Mobtown's oldest sushi purveyors have two full-service restaurants: in a downtown townhouse and on the water in Fells Point. The view's better in Fells, but parking is much easier downtown; the service and sushi are great at both. Take off your shoes, fold your legs under a low table, and let the clean flavors of raw fish rid you of the nasty. People say the tempura is good, and there are all manner of complicated rolls on the menu, if you're into that sort of thing, but with seafood this fresh, why spoil it? Just chase the yellowtail with sake, and then order some more yellowtail.
