Just finished seeing an opera at the Vienna State Opera and looking for a drink and found The Blaue Bar. Reservations are recommended but the maître d’ found us a table just outside in the red room. We were so pleased we went back a second time when it was quieter and had drinks at the Blaue Bar too. The Blue room decor is spectacular with blue surroundings. The red room is likewise beautifully decorated in red. The service was impeccable - friendly and attentive, evening when it was extremely busy. The cocktails were tasty, especially the champagne cocktail. the free snacks a welcome treat.
