The actual name of the place is Adega Rio Douro (since it’s facing the river) but everyone knows it by Tasca da Piedade, named after the owner Mrs. Piedade. It’s also known for having “fado vadio” - traditional Portuguese music, here sang by non-professionals every Tuesday in the afternoon from 4pm until 7pm.
While the music flows you can try a lot of Portuguese “petiscos”, such as stewed chicken guizzards, meat croquettes, “bifanas” and the crown jewel “iscas de bacalhau” - boiled codfish loin enveloped in a parsley omelette. The symbiosis between food and music is guaranteed, as everything here is done with passion. You might even be lucky to listen to the owner singing a few “fados”.
