If you EVER get a chance try the Sprüngli truffe de jour. Only place I've ever seen 'em is at the Zurich airport. They do not travel well and aren't exported.

This site says that you *can* order Sprungli products online and that they will ship to the US! Those mini-macaroons look yummy, too! (If mini-macaroon mention is hijacking the thread, I apologize. Some things make me think about other things.)
