Vienna Beef hot dogs in O'Hare?

Does anyone know whether the stand called Chicago Style Hot Dogs in Terminal One serves Vienna Beef?

I am assuming that Gold Coast Dogs in Terminals Three and Five do, but if anyone has any knowledge of how closely they conform at O'Hare to the Vienna Beef standard Chicago dog?

And natural casing or skinless?

I need to advise a friend with a short layover.

Was in Terminal 1 at O'Hare yesterday. There is definitely a Vienna Beef joint (not sure of the name) in the C Concourse, down in the direction of the Berghoff outpost from the escalators. They have a Vienna Beef poster/sign (same one, or similar to the one, in your post here) showing all of the classic Chicago dog toppings and appeared to have all the fixings when I peeked over the counter.

Thanks! That's probably the Chicago-Style place listed here.

I was amused to run across this blog reviewing Chicago Taste, a hot dog stand in L.A., which complains about all the Vienna Beef signs: "We couldn't imagine advertising an 'Authentic Chicago Style Hot Dog' in Chicago."
