The corner with the lady and the pram
Location: Linienstrasse and Gormannstrasse, Berlin
The key scene between Lola and the lady with the pram happens on the southwest corner of Linienstrasse and Gormannstrasse.
The area has changed considerably since the film, with lots of road signs, new apartment buildings etc. But you can identify this location via the surrounding buildings, like the HanseMerkur place of business (yes, it is still there) and the distinctive yellow brick tessellation along the top of the wall.
