As most of you know, I grew up in Russia, and Kinder Eggs were precious bits of treasure from the distant and mysterious west. (Not too far west, but far enough to be awesome.) Chocolate candy? Amazingly tiny detailed toy? The joy of unpeeling crinkly foil?
Maybe that last one was just for kids with slight OCD, like me.
Anyway, Kinder Eggs remind me of everything awesome about childhood, and I buy one time to time at a local Russian/Euro Deli store. Every Russian store I've been to sells them, so you should give it a try.
Sadly, those toys are nowhere near as amusing as they were when I was a kid. Oh well, nostalgia (and chocolate) are still delicious.
