Swiss has the very best chocolate. Ever tasted the Lindt Excellence Natural Orange? Import it. You´ll love it.
I´m getting addicted since I couldn´t get no choc in Granada, Nicaragua. Amazing, a city of 20,000+ people without chocolate. Sure, there were choc cookies. But no plain choc. I bought fresh choc milk at the market (which is a thing you shouldn´t do). You sip it out of little plastic bags there.
Anyhow.. the Zurich airport was probably the most boring thing I´ve ever seen after being to Central America. But their choc is the best.
