The menu runs through dishes like the Maine Lobster Roll on toasted brioche, served hot with butter or cold with mayo, Wellfleet Clam Chowder with salt pork and thyme, and a Bluefin 'Coyne' Crostini with tuna tartare on Iggy's baguette. The N.O.B. Clambake stacks a whole two-pound Maine lobster with clams, chorizo, and sweet corn, while the Neptune Johnnycake comes topped with honey butter and sturgeon caviar. Produce comes from named New England farms — Verrill Farm, Ward's Berry Farm, Maplebrook Farms — alongside house-made tartar sauce and a daily shellfish selection.
Neptune Oyster was a James Beard Foundation Outstanding Restaurant semifinalist in 2020, and Michelin selected it for its guide in 2025.
