A huge cabaret revue that makes full use of the largest stage in the world, Friedrichstadtpalast also has a comedy club in its basement. For those who may not know, Cabaret was a 20th century staple of German entertainment known for making humor out of and satirizing serious issues. These days, the modernized cabaret shows are somewhere in the ballpark of a risque adult circus or a Cirque du Soleil performance, on par with Vegas-style shows in their production value, excellent choreography, a variety of special effects, and beautiful male and female performers.
There are also regular children's performances and festival regalia, so it is best to check the official site for what's on. Tickets for the main showings can range anywhere from $25-$145 USD depending on seating, day of the week, and added amenities.
