Not a great variety of food options. Especially not at reasonable prices. Most of the airport is given over to designer/high end luxury stores. Wifi is limited. Wouldn't recommend for a transfer.
Buy foreign exchange @Credit Suisse (Check-In 2). But beware. They charge 5 CHF for non-customers and you're obliged to pay in cash! That's another surcharge of 2 CHF for the ATM. #sigh
