Burgers might be one of the most under rated foods. Of course that's only because there are probably a million ways to prepare one.
In Ann Arbor, Michigan, there's this place called Krazy Jim's Blimpy Burgers , only good way to describe them is greasy , with virtually anything you might ever want on them ( Ok, that's a exaggeration) they are made to order and cooked while you stand there. You can get anything from a Double (paddy) to a Quint(or more if you dare) The original location was very near to the campus of the University of Michigan, and during busy times of the day, if you didn't order correctly you'd pretty much get thrown out of the place, at the very least get chastised...
Their motto/slogan "Cheaper Than Food"
For a sense of what the Krazy Jim's experience is like... you can see the place on a episode of Dinners Drivins and Dives.
