I really love Portuguese food, and especially petiscos (snacks).
Almost every weekend, there’s a fair with Portuguese products. You can try sausages, ham, cheese, olive oil, bread, and many flavors of jelly like pumpkin or tomato. And of course you will need a drink—try a Portuguese wine (red, white, green, or rosé) or ask for a sangria.
These fairs can happen anywhere—maybe at Praça da Figueira, Rossio, or Campo Pequeno.
