As far as the Milwaukee area, I've gone out of my way to get other places in Wisconsin by going to Kopp's first. I once took a detour through Milwaukee from St. Paul to Phoenix to go to Kopp's and visit Brian. Mader's was a place my family went to a lot when we went down to Milwaukee (we were from Oshkosh). Pretty solid German food. As for Oshkosh, I have two shout-outs. First, Doctor Benzie's Pizza. I went there about once a week from 10-12 years of age, and every time I go back to visit my dad. Really solid pizza, they pack the toppings on huge, almost like a deep dish without the sides sometimes. Great, friendly staff. Second, Two Brothers Restaurant just off of 41 on Highway 21. Run by Greek immigrants, it has nothing but 50 different awesome greasy spoon menu items. Their gyro omlette is to die for. They moved to the building across the street recently (it used to be a Big Boy), but I assume the greasy awesomeness is still the same.
