Does anyone remember the name of that roadside restaurant they had in the 60's and 70's that sold the most amazing chocolate sundaes?

The chocolate syrup they used was really deliciously special. I’ve never tasted anything like it. What I’m really looking for is a recipe for it….but I can’t remember the name of the restaurant. When we were on family trips, Dad would always stop there at least once…it was always just off the highway. Orange roof??
