The Pine Tree State isn't short of retro dining cars, but A1 Diner, built in 1946, is up there with the most charming. With its pastel yellow exterior, blue vinyl booths and bar stools, neon clock and floral print tablecloths, it’s cheery and nostalgic. The food is suitably eclectic too, with fish tacos and a scallop BLT (scallop, bacon, lettuce and tomato between two pieces of toast) being the top choices.
