Boston’s dearth of waterfront watering holes is slowly being remedied by development in South Boston—Sam’s at Louis, Whiskey Priest. But a weathered old friend is still the darling in this category. The Barking Crab is a funky, coastal-style clam shack and the perfect place to sip Sam Adams and soak up the sunshine and salt air. Dress in your weekend worst: T-shirt, tattered jeans, flip-flops. The relaxed vibe provides a welcome escape from the rules of the city.
