3. The New York Library at the Iroquois Hotel, 49 West 44th Street

This little antique library only contains books about New York, and usually has delicious apple cider on offer in the winter. In a room just off the lobby, it’s primarily for guests, but visitors to the hotel’s Lantern’s Keep cocktail lounge can also browse its titles, such as Great Blizzards of New York City, whilst sheltering from Snowpocalypse.
