New York City bills itself as the "Capitol of the World" and it's easy to see why. Walking down any one street in Manhattan will treat you to more theaters, restaurants, shops, museums, and attractions than your poor, overloaded brain can handle all at once. Whether you're in town to visit a relative or trade on gold bullion futures, you're going to want to take in the city. Here are some of the biggest highlights.

Sightseeing

There are dozens of bus and boat tour operators in the city that make a great gift certificate ideas for anyone visiting the city. In a single afternoon you can take in the Statue of Liberty, the Brooklyn Bridge, the United Nations, Times Square, the Empire State Building, Central Park, and the World Trade Center Memorial. Each of these attractions offers its own tours as well, so you could easily spend a whole week just visiting the city's largest draws.

Museums

Arguably one of the finest cities in the world for museums, you'll want to take some time off from selling estate jewelry to visit such iconic institutions as the Metropolitan Museum of Art, the Natural History Museum, the Guggenheim Museum of modern art, the Intrepid Air and Space Museum (located on a real aircraft carrier!) and the Ellis Island Immigration Museum. There are literally hundreds of museums, small and large, on a range of subjects. Try some of the more unknown, like the Museum of Sex or the Museum of Biblical Art.

Sports and Theater

Put your cell phones away in their Motorola leather cases and take the evening off to see a show. If you're a sports fan, why not attend a baseball, basketball, football or hockey game? New York's Yankees, Knicks, Giants, and Rangers are some of the best teams in their leagues. There are also numerous Broadway shows on at any one time and special events, ballets, concerts, and operas at major venues like Lincoln Center, and Radio City Music Hall.

Shopping and Dining

From Times Square to the upscale retailers on 5th avenue to retail giant Macy's to the eclectic shops of the outer boroughs, you can get anything in New York City. Follow the wall lettering to find some of the best eateries in the nation when you get tired, ranging in cuisine from local pizza, cheesecake, and hotdog carts to five-star food from every nation under the sun.
