João Santos: Nice viewing point with a beer garden, ideal for a drink with a wonderful view over Lisbon. Must see for tourists, mandatory occasional visit for locals. Free, except for drinks at the beer garden.
Cris: Chill out music and a great view to the Tagus river.the chairs are old train seats witch give it a special look. Beer is cheap (2€) and they serve light meals (brunch, salads, sandwiches...) Best ti
