First and foremost, their burgers are INCREDIBLE and that is reason enough to go check it out!
I would actually give this place a 3.5 if that were possible. I docked it because it has a limited menu with mostly fried food, not many healthy dining options, but then again I'm not sure why anyone would go there for anything other than a burger. It is also definitely a dive, the bathrooms are a little scary, but the burger ranks right up there with the best in the Madison area.
