At Handlarn in Lilla Alby you can buy food imported from Germany. A lot of the selection in this store is German, all from bread to candy and cakes. My favourite is the Frucht kuche.
And it's cheap too...
At Tuletorget you will find some shops with art and antiques, Art of Iron is one of them.
Another shop worth a visit at Tuletorget is Gammalt & Nytt.
