A&W Drive-In 3

I used to love this place as a kid because it was different.  They used to bring the food to the car on rollerskates and hook it to our window.  I thought that was very cool.  I remember the frosty mug filled with rootbeer was quite yummy but don't remember much else about the taste of their food.  Don't see them around much anymore, guess they weren't that good!
