This dockside restaurant has a charming historic patina, as it is part of an actual fishing club headquartered in an 18th-century military Cartagena fortress, San Sebastián del Pastelillo. Sit at outdoor tables with views of the city, the bay, and the club’s private marina and pier (some of your fellow patrons arrive by boat!), and dine on freshly caught seafood. On weekends, live music—jazz, bossa nova, and flamenco—animates the scene.
