Backery next to Edeka is great. Good coffee and surprisingly reasonable prices in comparison with the other cafes at the airport. Perfect for early morning flights!
If you have a long time to wait for flight, go upstairs and grab a beer from "la terrasse" restaurant. There you can also use the free electricity for most needed "charging".
Free Wi-Fi (Mobilcom) for 1 hour. If you have more than one email address you have more free Wi-Fi ;-)
