They might have one fish dish, I can't recall (maybe some salmon), but mostly it's sausages and schnitzel and such. It's heavy on the meat - they even have like a pasta salad with some kind of wurst sausage in it that I really love. There are potatoes and spaetzle (like fried egg noodles) and such. Honestly, the best thing is a desert - the apple strudel (make sure to douse it in the sauce)!
Anyway, fish should be easy to avoid here, and the rest of the food is all delicious!
