I get "Alt-Oberurseler Brauhaus" = "Old Oberursel Brewery" (or literally "brewhouse") and "Jägerschnitzel" = Hunter's Cutlet, but one thing puzzles me: is Schnitzel always breaded, across German cuisines? Also is it usually pork? I ask because chicken schnitzel is something my Jewish relatives would make, and I wonder if using chicken instead of pork was something that only Jews did.

Gemerally Schnitzel is breaded in german (and austrian) cuisine. Normaly Schnitzel is made from Pork or veal. But it can also be made from chicken for jews and muslims. And some people eat chicken schnitzel because they just prefer chicken.

Oof... This is considered a cardinal sin here in Austria: putting sauce onto a breaded Schnitzel, because it takes away the crispyness.
It's pretty much considered the "pineapple on a pizza" thing here.

If you order a Jägerschnitzel here with a sauce you will always get it without bread.
And if you ask for a sauce on your Wiener-Schnitzel here.... Well, you might get it, together with a raised eye-brow from the waiter probably. ^^;

Yeah, I guess those are regional differences.
