Ruhigerstrasse

You open the door to the derelict building opposite the Cross Hands on Ruhigerstrasse. In the fading light you can just make out the furry ears and twitching nose of the Great White Rabbit.

'Well done,' it says. 'You have found me. It's a bit rough down this way so be careful on your way back. If you're looking for the golden egg then I must tell you your next clue.'

'Go find a map maker and look through his Large Selection of Maps. That will show you where to go next.'

And before you can ask a question, the Great White Rabbit is no longer there.
