Foz do Douro

This stretch of Foz faces the open ocean along the Avenida do Brasil, where the Atlantic promenade fills with joggers, surfers and Porto families taking the sea air on a Sunday. The dining here is more relaxed than the river side, geared to the seafront: glass-walled rooms catching the sunset, terraces a few steps from the sand, and kitchens that range from polished seafood to easy all-day cooking. It is where the city comes to eat with the waves in view rather than to make an occasion of it. Order grilled fish or a long lunch and watch the surf break against the rocks below.
