Munich airport is just another example of the Bavarian term 'gemutlichkeit' (sp) as it applies to air travel.
The airport is very nice, very easy to negotiate and is a much better option than FRA (which is functional but ugly). I always try to pad my time there just a little so I can enjoy a weisswurst and a lager at the Airbrau restaurant between the terminals.
I can't say enough good things about Munich, Munich airport, or Bayern in general.
