German restaurants in Frankfurt Intl. Airport?

The Paulaner restaurant in the Squaire business center/regional train station
area would seem to be an obvious choice. Just keep an eye on the clock
if you go there, as you will exit secure area and have to reclear security after
your meal. Roundtrip is probably a half-hour walk and the security lines at
FRA can be nasty at times

What terminal are you using for your flight. Although this is a good restaurant in fact we ate there last week it is a very long walk. I think your on the edge of comfort depending on what terminal your using.
