No they are not made oit of viena sausauges!!! Those things aren' t even real food. Vienna is a trade name., they are a pure beef kosher frank, which are on a level with Nathans.Fly. nope. had my last nathans about three months ago, there is a guy who has a hot dod wagon, ande was at the clinic in bowling green.Its always a promise to myself when I go up north to have at least one dog and one vienna polish, and of course, if I can still swallow, a Gyro!
