Better get a cab or a short tram ride and have a nice view.
On the other hand, no better place to get your "belegte Broetchen" than the "Feinkost Bauer" delicatessen close to the central train station.
I really love this shop and the long-standing proprietors, you get everything from a simple snack to tinned caviar and a good assortment of fine wines and champagne under one roof.
