It's not exactly the same but my city has "robot pizza machines" that are basically glorified vending machines with pizza that's cooked daily and reheated on demand. It works really well for the company because they specifically put the machines in neighbourhoods where people go to drink.
I think as far as automated pizza goes, that's the best way to do it.
Kind of like the Japanese vending machines. I think those kind of thing are awesome (and practical if you need a fast bite) and would love to see them in America more.
