Hidden inside the iconic Hotel Sacher, Blaue Bar is one of Vienna's great little surprises – an elevated, prestige drinking den hidden within a remarkably small room dressed almost entirely in blue, just as its name promises. It's the ideal place for a perfectly made martini accompanied by traditional Austrian bite-sized comforts: finger-food Schnitzel, a sausage with a Semmel, and, naturally, a slice of Sacher Torte to finish. Whether before or after a performance at the nearby Vienna State Opera (if that's your sort of evening) or simply as a more traditional stop on a night out, it feels effortlessly right. This intimate little bar works magic tricks on visitors, turning a quick drink into one of the most memorable moments of a Vienna escape.
