Where you have a drink is as important as the environment where the bar is located, and the surroundings of Bar Eldorado are unbeatable. It is in a charming historic town with a few streets where hardly anyone goes and which are full of tranquility. To get there you will have to be a bit flexible as the streets are winding and will make you work a little to get to there, but it is the historic town of Castelsardo. The most striking feature is its interior bar, which is over two floors and is very cozy but not the best way to have a drink in this place, which for me, is out on the terrace. Another major reason to have a drink in this bar is that the person who greeted us was very friendly and nice.
