Subways, trains, astronomy and oysters all in one place

Noteworthy for: Based on the number of platforms - 44 with 67 tracks - Grand Central is the world’s largest train station.

After having been rebuilt twice, the current Grand Central Terminal was completed in 1913. Embedded in the opulent facade are three 48-foot sculptures of Greek gods Hercules, Minerva and Mercury, and a clock made of the world's largest piece of Tiffany glass.

Inside is the Grand Concourse, with a four-faced opal clock (valued at USD 10-20 million) atop the information booth. Be sure to gaze up at the stunning painting of the constellation-filled heavens on the ceiling. In the 1930s, nicotine obscured the mural so badly that it was repainted - but go to Michael Jordan’s Steak House (on the second floor balcony) to see a small square workers left untouched to prove how dirty the original was.

The terminal has a slew of retail shops, delis and bakeries, and downstairs is a New York legend: the Grand Central Oyster Bar, serving fresh, delicious seafood and oysters from all over North America.
