MOSHULU Penn’s Landing, 401 South Columbus Boulevard, Philadelphia; 215- 923-2500; www.moshulu.com; $56

Aboard the Moshulu, the world’s largest four-masted sailing ship, those booking the chef’s private dining room can gather around a table in the former captain’s quarters that seats up to 20 in a hideaway with portholes. Like other diners on the 102-year-old ship, they can follow chef Ralph Fernandez’s contemporary American fare with an after-dinner menu—eight desserts, each paired with a sweet wine, port or spirit. Book the room for New Year’s Eve or the Fourth of July, and you’re only steps away from a privileged on-deck view of the city’s Delaware River fireworks display.
