Brooks bought Lindburger's, a local institution but total dive, in 2010 and turned it into Brooks Burgers (as fans call it).
"It was a very greasy spoon sorta feel, like a dive on the corner, which I liked," Brooks tells CNBC Make It. "We cleaned it up but kept it so it felt like an old, beat-up restaurant.
"I decided on burgers and dogs because I knew a lot about the meat market and I also loved the history of the old burger joint," Brooks says. "We made [it] more approachable and we improved all the food."
