The Union Oyster House is the oldest restaurant in Boston and the oldest restaurant in continuous service in the U.S.  The doors have always been open to diners since 1826.

The Union Oyster House, located on the Freedom Trail, near Faneuil Hall, enjoys the unique distinction of being America's oldest restaurant. This Boston fixture, housed in a building dating back to Pre-Revolutionary days, started serving food in 1826 and has continued ever since with the stalls and oyster bar, where Daniel Webster was a constant customer, in their original positions.
