The architectural couple Ralf Schüler and Ursulina Schüller-Witte designed a futuristic tower restaurant on top of the roof of the Schloßstraße metro station in 1976.
The guests looked over the dream of mobility of that time, namely a fly-over that leads the viewer to the entrance and exit complex of the A103 motorway located further away. Due to its gastronomic interpretation and its resemblance to a paintbrush, the tower soon got the nickname Bierpinsel (German for "beer brush").
