The neighborhood's second New England fish house (the result of a split between Pearl Oyster Bar's partners) proves you can't have too much of a good thing. Casual Mary's Fish Camp usually has a wait for fried oysters, chowder, moist grilled catches of the day, and, of course, the sweet lobster roll with impeccable frites. A neighborhood favorite is the lobster potpie, which runs out early. Reservations not accepted. Subway: 1, 9 to Christopher St.-Sheridan Sq.
