Probably being picky here, but I believe the "Wienerschnitzel" actually translates into something like "Vienna Cutlet" or "Viennese-style chop". In most parts of German-speaking Europe that I'm familiar with, if you order a Wienerschnitzel, you'll be served something like a somewhat higher quality breaded, fried tenderloin.
Thing to consider is that "Wiener" doesn't refer to the type of sausage we're familiar with either, (although that also could be considered to come from the German word for the city), but rather from "Wien", which is the German name for the Austrian capital city. "Schnitzel" does, however, does have a bit of the "little" associated with it, in the sense that it refers to a diminutive "cut".
By the way, as I recall, there was a fairly popular chain of "Wienerschnitzel" casual restaurants in southern Germany as well. Whether they part of the same chain you're speaking of, I couldn't say.
Gosh aren't you glad that I interrupted?!
