Originally it was a Top Cat Fast Food Restaurant? It was Tom Boy Hamburgers originally, evolving into Top Boy Hamburgers (saved money by not changing the sign too much). The outside sign was repurposed from the buildings first incarnation as Top Boy? Hamburgers. Jim also owned for Big Boy Beer and Burger Grand Rapids Eats and Treats that became Sensations. D-J’s was named such for the early partnership of Denny and Jim. The ‘D was Denny Patterson and ‘J was Jim Gibfried, both D&J taught at CC. It was a hopping spot.
