The place is called Luke's Market Street Italian Sandwiches at 117 W Market St, Elkhorn, WI 53121 (262) 723-4676. They have huge Italian Beef & char-broiled Italian Sausage sandwiches. I believe the sausage is Scala brand, or a brand that is very close. The sammys are 7" long, & the Double Sausage has got to be nearly 3/4 lb of sausage. They also offer Pepper & Egg sammys year round. They have a Chicago style dog, but it's not Vienna, so meh....
It's tough being a Bears fan in Cheesehead land!
