Green Bay Eating

So I went to Green Bay last weekend and made a point of ordering butterburgers where possible. I have to say, though, overall they weren’t that good. They looked good. They even tasted alright. But they just weren’t enough to justify the added decadence of buttered burger and bun.

Photo that is self-explanatory, below, from the diner known as Kroll’s across the street from Packer’s Lambeau field. One question, though; why is this, of all things, still a regional phenomenon?
