Aquagrill's friendly staff and extensive all-things-marine menu place it among the best. Chef-owner Jeremy Marshall mans the stove, while his wife, Jennifer, works the host stand. Specialties include roasted Dungeness crab cake napoleon and falafel-crusted salmon served on hummus with tomato and cucumber not to mention the grilled fresh fish and a rotating selection of East and West Coast oysters. The chocolate tasting plate is a seductive end, but you may just want to have a few more kumamotos: they're sweet enough for a dessert. Reservations essential. Subway: C, E to Spring St.
