Fodor's Expert Review Bar Los Diamantes

This lively bar (with a sister branch on Plaza Nueva) is a big favorite with locals and draws crowds whatever the time of year. Specialties include fried fish and seafood—try the surtido de pescado (assortment of fried fish) to sample the best—as well as sesos (fried lambs' brains). No reservations are taken and seating is inside or outside with views of the Plaza de Bib-Rambla, so arrive early (1:30 pm or 8 pm) to be sure of some bar space or a tall table outside. Even when it's crowded, the service comes with a smile.
