There is a quite good German bakery on Oxford Rd and Malibongwe crossing (next to the German Butcher Seemann's) - going west on Oxford, cross Malibongwe and it is on your right hand side entering a small guarded parking lot. I think it is Hammer Avenue.
Then I have been shown a nice bakery in a open air mall where the German butchery Goodmann's is. That is on Republic Road, off Main. Sorry, but I don't know the mall's name. Maybe good to ask for the Butchery, then you should find it. If I find out more, I will post again.
