One of the busiest train stations in the world, this architectural monument to American transportation was saved from destruction in 1978 by a U.S. Supreme Court decision. Its Renaissance-style architecture creates a strangely peaceful backdrop for the dance of thousands of frenetic commuters. The creamy-rose, Tennessee-marble floors gleam, as do the hundreds of bulbs in the brass chandeliers. The Sky Ceiling is a heart-stopper: The aquamarine image of the night sky is speckled with tiny lights for stars, and major constellations are outlined in gold. There are more than 68 shops and 35 restaurants, including the famed Grand Central Oyster Bar. The Grand Central Market has vendors selling produce, cheeses, baked goods and gourmet treats from around the world. Group tours (US$5 per person for more than 10 people, or a minimum of US$50 for the group) must be booked in advance (phone 212-340-2345 or online).
