In the location's words:

The museum, directly on Zülpicher Platz, not only offers a proper bar feeling. Here you can also dance, listen to concerts and sing yourself! Four days a week, the museum offers a karaoke evening from 10 pm. On Wednesdays, Thursdays, Fridays and Saturdays, you can choose between 32,000 music titles of all kinds. With your favorite hits in your pocket and a little courage, you can have a great karaoke evening here!
