Some of those weren't really automated, but rather worked more like vending machines. Weirdly, I've seen an updated version of these in hospitals. In addition, I've seen vending machines with cafeteria sandwiches and frozen microwave dinners.
For clarity, what I more refer to is kitchens without human intervention save for mechanics. The machines make burgers, fries, and whatnot. It seems the first wave is going more to replace the cashier, though: McDonalds has introduced touch-screen ordering stations and grocery stores have self-checkouts.
