We had a wonderful evening at the Fortress! The concert was a solid 2 hours of beautiful music in a splendid, intimate setting. There are many music venues in Salzburg, but I do think this one is very beautiful. I know some other folks have criticized the food included with the dinner, but we had a very good experience. It's not 5-star food, but it was plentiful and very good and the setting outdoors on the terrace overlooking Salzburg and the Alps is worth it. This was a highlight of our stay in Salzburg and we highly recommend it for music lovers!
