Oyster House, one of the city’s best raw bars, is perfect for nearly any occasion. Come for post-work lobster rolls and oysters with a colleague or client. Walk in with a friend or two when you want to chow down on shellfish, split a bottle of wine, and people-watch near the picture windows. Or come with a big group and get the New England-style clambake–buckets of clams, shrimp, lobsters, and corn dripping in garlic chive butter is dumped onto the table for everyone to share, family style.
