I have been living in Michigan and no one seems to know what a breaded tenderloin sandwich is. I have been searching for a drive-in, or any place, that serves one for a long time, but it seems they have all become part of the past.
I would love to have one right now, with a big rootbeer and onion rings. Yum Yum!
Try any of the Culvers drive in restaurants. They all have breaded pork tenderloins. Not as good as Iowa but pretty close! You have to look for it on their menu
