Hi,
I'm going to Poland for Christmas and would like to buy something nice for my nephew.
He's not even 2 yet but because I really don't see him often

I would like to get something special for him and I am thinking of something simple but educational - a set of blocks or a game he can grow up with and not the kind of rubbish plastic cars he will use for a week and put aside.
Where should I look for such store in Zurich?
Thanks for your help
