Klagenfurt, Austria (KLU): If traveling there from Klagenfurt Hauptbanhof, don't look for the famous (at least on Ryanair.com) bus to the airport at the busbanhof just to the left of the station, look over to the right, it stops at the corner of the street, near the taxi queue.

Once there, they have one of the best airport restaurants in Europe. Go up the spiral staircase, just to the right of checkin, and they have a nice terrace where you can see the mountains, and have a cold beer and brats. Excellent Fare!
