Have a snail snack at the marina
Take it from a local: stewed in herbs and garlic, snails are a delicious (and entertaining) snack that goes perfectly with beer. The best place to get them is at the marina, in the Parque das Nações neighbourhood. This quiet location has all the perks of the riverfront, with a wide and long promenade, minus the crowds you would normally find in such a beautiful setting. Just pick a table by the river, soak up the views and nibble away. The best way to get here is by car, and parking is always available. Otherwise, you can catch the subway to Estação do Oriente (red line) and walk the rest of the way along the river. The marina has many restaurants lined up along the promenade, with Mestre Doce a particularly good option for trying snails.
