Barcelona’s oldest cocktail bar hides in an inconspicuous side street off Les Rambles. Opened in 1933 by Miguel Boadas, who had once tended bar in the legendary Floridita in Havana, its Art Deco interior has remained unchanged. As you enter through the wooden door, you might think you’ve traveled back in time to the Golden Age of Cocktails. There is no menu, but the bartenders mix what are probably the best daiquiris and mojitos in town.
