Even if you're not catching one of the Metro-North commuter trains, make New York City's Grand Central Station part of your itinerary. Finished in 1913 and beautifully renovated ten years ago, this Beaux Arts masterpiece features a 12-story vibrant blue ceiling on which the stars of the zodiac are traced in 24-karat gold and a central kiosk over which the landmark brass clock is perched. Aside from the gorgeous main concourse, Grand Central offers a very good dining concourse on the lower level; top restaurants including Michael Jordan's The Steakhouse, the famous Oyster Bar & Restaurant (a glitzy bar), and Campbell Apartment; and a gourmet food market, Grand Central Market. You can enjoy a guided tour ($10 suggested donation) of the terminal given by the Municipal Art Society.
