I'm not going to go on my rant about this, but it looks like the Vortex Bar & Grill in Atlanta has a megaburger to end all megaburgers (until the next megaburger-wielding asshole steps forward): "two fried eggs, four slices of American cheese, and five slices of bacon, with two grilled cheese sandwiches replacing the buns."
Adam Richman of Man vs. Food ate the thing. Eat Me Daily has video.
Hmm, grilled cheese sandwich replacing buns? Sounds familiar.
