No. The concept of a butter burger scares me. But, there's so little to choose from, here, I can't be too picky.
I don't eat red meat so I've never tried one. They have a HUGE menu, it's more like McDonald's meets Dairy Queen meets Bob Evans really. I usually get the kids meal, either grilled cheese or chicken tenders.
There is probably one near you, they are everywhere in Wisconsin. There are only like 5 in Ohio but one of them is only about 5 minutes from me.
