Summary
Over an average twelve-month period, the restaurant [Grand Central Oyster Bar] serves between fifty and seventy-five varieties of oysters. Each is somewhat different in appearance and taste, but nearly all are variants of the eastern oyster or Crassostrea virginica, the species native to the Atlantic and Gulf seaboards.
