One of the highlights in Vienna is seeing an opera performance at the State Opera House. Even if you’re not into opera the interior of the building is worth seeing. It’s in excellent condition and makes you feel as if you’ve stepped back in time into the gilded age. For a mere 3 EUR you can get standing room tickets and enjoy the show. There is a dress code however: don’t wear shorts. And do wear comfortable shoes, the standing will wear you down. The State Opera House is located at the “Opera” U-Bahn (metro) station and there’s an opera performance on nearly every night.
