"One of Barcelona 's most exclusive streets, Passeig de Gràcia is home to modernista masterpieces like La Pedrera and Casa Batlló as well as the massive luxury storefronts of brands such as Louis Vuitton, Burberry, Mandarina Duck, and Adolfo Domínguez. That said, you'll also find more affordable shops like Zara and H&M for mere mortals. This is a great place to perch on a mosaic modernista park bench and people-watch. The mix of wealthy locals, fashionistas, and tourists of all shapes and sizes makes it especially entertaining, even for Barcelona ."
