Grand Central Terminal sees millions of commuters each week, but tourists shouldn't miss out on this New York City gem. Home to several notable bars and eateries, remember to look up when you're in the main concourse -- the constellations featured on the ceiling are among the best star gazing in the city. If you're feeling indulgent (& well dressed!), enjoy a cocktail at Campbell's Apartment and get a glimpse into the hidden office of a 1930s tycoon. Our visitors guide is loaded with tips and ideas for what to explore, where to eat, and more.
