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.

May is comfortable for Ribeira, Gaia tastings, and Cedofeita galleries, though showers remain common.
City overview
Porto is Northern Portugal's Douro River city, a steep granite-and-tile port where medieval lanes, baroque churches, steel bridges, and Gaia wine lodges face each other across the water. Ribeira and Baixa give the compact historic core, Vila Nova de Gaia holds the port-wine cellars, and Cedofeita and Foz do Douro show the art, boutique, and Atlantic edges.
Food & drink
Porto eating is hearty: francesinha, tripas à moda do Porto, bacalhau, caldo verde, bifanas, octopus rice, and pastéis de nata all matter. Mercado do Bolhão, Cais da Ribeira restaurants, Conga bifanas, and Gaia port lodges make a useful first food route.

Neighborhoods
1Ribeira and Sé
Ribeira and Sé are steep, old, and scenic, with river terraces, the cathedral, medieval lanes, São Bento, and bridge views packed into short climbs.
2Baixa and Aliados
Baixa is central Porto, with Avenida dos Aliados, Clérigos, Livraria Lello, Bolhão, cafes, tiled churches, and the busiest metro links.

4Cedofeita and Miguel Bombarda
Cedofeita is the art-and-boutique quarter, anchored by Rua Miguel Bombarda galleries, concept shops, brunch spots, and lower-key nightlife.
5Foz do Douro

Getting around
Metro do Porto and the Andante card cover the airport, Campanhã, São Bento, Trindade, Boavista, and Gaia, but Ribeira and Baixa still require steep walking. Tram Line 1 is scenic to Foz, the Funicular dos Guindais saves one climb from Ribeira, and trains from São Bento handle Braga and Guimarães.
