I found this cherry liquor to be just yummy. You can try it in a place called "A Ginjinha". It is about 1.50 euros per cup. It is to the right of the theater (if viewed from the front) from the Rossio square.
In Carcavelos beach, then after to the "Forte de São Julião" is the Bar Moinho. It is a bar to chill out in ... you can have breakfast, dinner, drinks, eat and admire the beach from your special terrace. You choose where you want to admire the sea, whether from their sofas, chairs, tables and you can accompany it with mojito, caipirinha or fruit juice. The same happens at Carcavelos, even if it's only for a coffee, it's worth going.
So far, the bar that I've most enjoyed in Cascais! First, I have to say it has a great location on the beach, and a wonderful sea view. The decor is nautical, without being cliched, and is very cozy. The employees are very friendly, always serving with a smile. They have great chicken sandwiches with different smoothies. All this, and more ... don't miss it!
Barrio Alto is one of the best places for drinks in Lisbon, as the atmosphere on the streets is very lively and there are plenty of places to choose from. We went to the Mojito Copany looking for some cheer and dancing after enjoying several hours of Fado. It's a place to dance Latin rhythms, it's decorated with pictures and musical instruments and they serve great caipirinhas and mojitos.
Following the recommendation of Almudena, we went to this spot that was full of people and had a beautiful atmosphere. We found a small empty place and a waitress that served us two beers .... she barely served us, though, so thank Godness we got our beers ourselves. It was about 12 pm when we left and only three guys had come over, they began to play chess. I guess that since 2011 the bar must have changed.
