If you watch romantic comedies set in New York City, you already know some good places: Tiffany's, the ice skating rink at Rockefeller Center, The Metropolitan Museum of Art, the top of the Empire State Building. The parks are great places for lovers, too; Central Park and Prospect Park are not only romantic, they're Romantic. Designed during the artistic period known as Romanticism, these parks are to landscape design what Frederic Chopin is to music and Nathaniel Hawthorne is to literature.
If you're looking for somewhere a little less traveled, try the "LOVE" sign on the corner of 54th and 6th or the fountain in front of Lincoln Center. Want more options? Pick up a copy of "Romantic New York City: A Guide to the Most Romantic Clubs, Restaurants, Bars and Hotels in New York City" by William King and Jimmy Hahn.
