I can’t recall ever seeing a Burger Chef restaurant back then. My family moved around the country several times over the years in the 70’s.
It’s possible they were operating in regions where there wasn’t a Burger King, and hence could offer the same Coca Cola movie tie-in promotions.
When I lived in New Jersey back in the late 70’s there were no Kentucky Fried Chicken locations to be found. But there was a burger chain called Gino’s that offered KFC food in addition to their own menu. That massively confused me as a kid. 😉

Thank you for the response and info …very interesting
