I love stopping in to Søstrene Grene for all kinds of random knick knacks and objects. Need cute…read morebaskets for organizing? Nicely flavored teas? Random kitchen supplies? Art materials? Kids' toys? They've got them all, and much more. And as a plus, everything's really affordably priced (even for Norway!)
Just be careful: the supply can change frequently, so if you see something you like--get it! They may not have it the next time you're there.
