Caffeine addicts flock to “Coffee O” for bracing espressos, a slice of coffee cake, and a smidgen of counterculture à la Falmouth and Woods Hole. Eggnog, apple cider, and other seasonal beverages, too. A retail shop serves all your chai- and coffee-related needs.
There’s also a prominent outpost in Woods Hole at 38 Water Street. You can’t miss it (508-540-8130).
