These Big Boys were Midwest operations. Notable, I guess, for their “Black Tar Ketchup.” Marcs ran Big Boys from 1958 to 1995.

In 1989, Marc's Big Boy Corporation was renamed Marc's Restaurants and a two-year experiment launched completely removing Big Boy at two of its stores, the test demonstrating no effect on business.

Totally unrelated, of course: In 1995, the company closed its last Big Boy operation.
