5. Grand Central Terminal Houses a Hidden, Gilded Age Bar

The Campbell Apartment in Grand Central Terminal serves as a testament to the grandiosity of another era. If appropriately attired, you can enter the room and sip on cocktails from the fin de siècle in this virtual museum to the opulence of New York’s high society of the past.

The apartment once belonged to John C. Campbell, a business tycoon; rumor has it that he used to sit behind his desk in his boxers, so that his trousers wouldn’t get wrinkled. The Campbell Apartment is also one of our favorite hidden bars in New York City.
