I like the quiet environment of the airport design in both Frankfurt and Zurich. Dark, hard floors. Dim lighting.
At Zurich, I also enjoy the high architectural glass silos, providing a view of the bottom (or top) floor. These periodic pauses sometimes have sculptures in them, reminding me of my own beautiful airport DEN.
Most of all, the prized Swiss chocolatier, Läderach, has a beautiful and well stocked store.
