When you go to Lisbon and you have a craving for seafood, cross the river. By taking the frequent commuter ferry across to the residential neighborhood of Cacilhas, you’ll not only avoid many of the other tourists, you’ll also pay about a third of what you’d spend on a similar dinner in the center of town. And the food! Lisbon portions are notoriously large. Here are our plates after we polished off just one of the many shellfish offerings we enjoyed in a multi-course seafood dinner for about $30 per person at Vale do Rio.
