"Serendipity 3, an Upper East Side restaurant-cum-soda fountain with marble-topped tables and Tiffany-style lamps, hasn’t changed all that much since it opened in 1954. You'll find everything from meatloaf to hamburgers, but it's the desserts that made the place famous. Share an elaborate, oversized sundae, a banana split, or the famed frozen hot chocolate or mochaccino. It's the perfect way to give the kiddos a Willy Wonka–style treat in summer after a few hours of sightseeing." - Sunshine Flint
