This was in the Pleasant Grove section of Dallas. The burger was sort of like a sloppy joe sandwich with mustard and very popular and delicious. They were sold at the Vel-Mar Drive-in and car-hops would come to your car. The popular drinks were Red Rover, Wildcat, and Silver Saddle. Each one had a little plastic animal hanging from the rim of the glass and kids and teens would collect them. (monkey, giraffe, donkey, and mermaid). They also had the best frosted mugs of root beer. I would love to have the receipe for the Dixie Burgers if anyone has it. Thank you!
