This location appears to have the best options in the terminal for a quick pre-flight meal. They have warm and cold options, like sandwiches, and made to order coffee. There is also a selection of candy bars and pre-wrapped items if you want to grab something. They also have bottled beer and will give you a glass to drink it out of.
I have had their hot chocolate, a beer and also warm food from them.
If you speak imperfect German to them, they will switch to English, which is fair because they are good at English because they are in the airport.
There is a board in their space that shows departure times and status, which is helpful if you choose to sit down and have your food/drink there. read more
