About Barcelona
City overview
Barcelona is the Catalan Mediterranean city where the Collserola hills, Montjuïc, and the old port frame Eixample blocks, Gothic lanes, and Barceloneta beaches. Its strongest days link Gaudí architecture in Eixample and Gràcia with medieval streets in the Gothic Quarter and El Born, then finish on the waterfront or a Poble-sec tapas crawl.
Food & drink
Barcelona food is Catalan before it is generic Spanish: pa amb tomaquet is bread rubbed with tomato, olive oil, and salt, bombas are fried potato-and-meat balls with brava sauce or allioli, and fideua swaps paella rice for short noodles. La Boqueria, Santa Caterina Market, Carrer de Blai in Poble-sec, Barceloneta seafood houses, and Gràcia plazas add escalivada, seafood rice, crema catalana, jamon, calcots in season, and vermouth with conservas.
