I have driven to Wisconsin from Illinois for some decent food.
Kilwin's in Lake Geneva has some 'came in my pants' quality Ice Cream - the best I've ever had anywhere. I had some scoops of oatmeal, coconut (AWESOME), some others - all excellent. If I was on death row this is what I would order.
Simple Cafe in LG is also good. Quite a few unique breakfast incorporating kimchee.
I've got the names of a couple other restaurants at home; I'll post the names later.
