Bird 'n Burger circa 1965
I'm looking for information on a chain concept called "Bird 'n' Burger", circa 1965-1969. It featured chicken, hamburgers, and pizza, and possibly soft serve "ice cream". There was one in Landover Hills, Maryland, at that time, and site still exists as a nursery--but the building has been obliterated. I'd like to know if there were any other locations.
(This might be so obscure that the moderators may delete this thread, and if so, I understand.)
