Sonic keeps the dream alive with girls on roller skates delivering burgers and fries to your car. It was like paradise to me, especially as a roller derby fan, except I don't own a vehicle and I seldom had an excuse/reason to dine there.

There used to be some restaurants using relatively large-scale (typically 45mm gauge) model railway kit to deliver food to your table. The wagons were large enough to put a basket-style meal or a couple of drinks in each one.
