I grew up in Davenport, Iowa, in the '80s. At the corner of Division Street and Kimberly Road was a local burger joint called BG's Charbroiled Burgers.
I haven't had them since I was in grade school, and all I can remember is that they did indeed have a charbroiled taste, completely different from the McDonald's and Wendy's that I had far more often, and were greasy as hell. Shiny silver wrappers that said simply "HAMBURGER" or "CHEESEBURGER" in a very '80s font (similar to the Dunkin' Donuts logo).
They closed so long ago that no amount of searching that I do turns up any record of them at all, other than posts that I myself have made elsewhere. The only proof I have of their existence is that a friend of my sister's used to work there as a cook.
Anyone remember BG's? Or Dean's, which was just a little ways down Division, on the other side of the intersection? Or Riefe's, which, hell, just closed a few years ago?
