Rua Nova da Trindade, near Bairro Alto

Calçada do Duque is a street made of hundreds of stairs, lined with lots of traditional Portuguese restaurants (not cheap). Background: Saint George’s Castle (Castelo de São Jorge), a wonderful view!

Almost downstairs, Calçada do Carmo: old men are selling Portuguese newspapers just in front of a sex shop.
