2. Oyster Bar, Grand Central Terminal

Located on the lower level of Grand Central Terminal, the Oyster Bar & Restaurant has been dishing out the freshest oysters and seafood dishes since 1913. Over a hundred years later, it remains a New York institution — famous not only for its seafood, but also for its adornment with Guastavino tiles. The tiles’ herringbone pattern takes center stage in this underground eatery, with lights running up and across the grand vaults.

After dining, patrons can step outside the restaurant and into the next Guastavino tile location. Warning: this one is a little “hush, hush!”
