"Waterfront dining on the cheap is the name of the game at James Beard award-winning Sullivan’s, where dining on a very nice lobster roll for under $30 is still possible. The menu also offers plenty of kid-friendly bites, plus there’s a fort to walk around at the original Southie location." - Tanya Edwards
