Serving fresh seafood to commuters since 1913, the Grand Central Oyster Bar and Restaurant is a testament to the perfection of fresh seafood served simply.  The oysters are of course delicious, but the lobster, clam chowder, and crab cakes are also worth a go.  The restaurant itself is in the lower concourse of the Terminal, and it's a fun way for tourists to explore the innards of Grand Central.
