City overview
Lisbon is a Tagus River capital built across seven hills, with Alfama lanes, Baixa Pombalina grids, Bairro Alto climbs, and Belém monuments showing how the 1755 earthquake and Atlantic navigation shaped the city. Baixa and Chiado make the central walking spine, Alfama and Graça hold the older Moorish street pattern, and Parque das Nações adds the Expo 98 riverfront east of the center.
Food & drink
Lisbon food centers on pastéis de nata, bacalhau à brás, grilled sardines, caldo verde, bifana sandwiches, amêijoas à Bulhão Pato, ginjinha, and seafood rice. Time Out Market in Mercado da Ribeira, Rua das Portas de Santo Antão, Belém pastry shops, Alfama fado restaurants, and Cais do Sodré counters give the most useful first eating route.

Madrid sits high on Spain's central plateau, with Sol, La Latina, Lavapiés, Malasaña, Chueca, Salamanca, Chamberí, Retiro, and Paseo del Arte linking royal power, late meals, football, art museums, plazas, and park life.

September is warm but wetter, good for beaches between showers and La Merce-season city energy.
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.
