I am looking for recommendations for a nice evening in Vienna - music, dinner, etc. Vienna is a stop on a Amawaterways cruise we are doing over Thanksgiving. The ship is in Vienna over night, which gives us time to do something on our own. The cruise organized concert sounds very touristy. And, unfortunately, we will be there on a Monday night and I'm not finding many forums with performances that night to book. We are comfortable striking out on our own and are looking for a special evening away from the boat. We can go casual or something more formal. Just something unique to Vienna. Any suggestions?
