Light years away from the mega-centers and nightclub lights of the Port Olimpic, La Barceloneta is a traditional hamlet of pescadors and meriners.With its narrow streets, small squares, and old bars, the neighborhood is a dip into the Barcelona of 150 years ago, where older people bring their chairs to the street and chat, watching passersby, and seafood restaurants serve a menu del dia based on the catch of the day.At the western end of Barceloneta is Passeig Joan de Borbó.
