The country’s oldest restaurant (since 1826) is on the Freedom Trail and gets enough tourists to justify a gift shop. The food is pricey—you’re paying for ye olde atmosphere—but the chowders and oyster options get consistently good marks. There are sit-down tables and counter seats around the oyster shucking bar. President John F. Kennedy apparently was a regular, and the upstairs dining room has a dedicated “Kennedy Booth” at the spot the restaurant says was his favorite.
