Bookmarks Rooftop Lounge at the Library Hotel

The fireplace, cozy sofas and club chairs at this rooftop bar suggest the decadent penthouse apartment you’ll probably never afford. The enclosed greenhouse and the outdoor terrace (in less frigid weather) are both ideal perches for sipping luxurious cocktails—such as the $12 Hemingway made with rum, mint and champagne—and enjoying the multimillion-dollar view of midtown’s soaring skyscrapers.
