Gilley’s Diner

About

Step into a slice of Portsmouth history at this teeny-tiny diner that’s been dishing out burgers, dogs, and fries since the 1940s. The inside is snug (think counter stools and not much else), but that’s part of the fun. Families love the no-frills comfort food, kids get a kick out of how different it feels from a “normal” restaurant, and the prices are refreshingly old-school too. It’s cash-only, kid-approved, and a quirky little slice of Portsmouth history you won’t find anywhere else.
