The old strip bar has (sadly, some say) been refurnished into a rock bar some nights during the week. Go for a troll down Langstrasse and enter if this is the occasion; there is no entry fee. Recommended!
Dance floor is small but since people tend to dance stoically to rock music, with common moves including the 3 second air-guitar, thigh slapping to the beat, head banging and hyperactive shoulder movements. This allows many people to come together in small areas and enjoy each others mirth, until the late hours of the night.
