For nightlife you have several options. If you're there during opera season and are lucky enough to have opera tickets eat an early dinner enjoy the performance and end with coffee and a Sacher torte at the cafe in the Hotel Sacher. Or you might go to the part of the central district known as the Bermuda Triangle where the small restaurants and the bars are open late. A third possibility would be to head for a Heurigen (a wine bar) for an evening of music and tasting of the year's new wine (Sturm).
