Nice try. They don't have a drive-thru.
But nearly all the Hutts around me have a drive through. Obviously, it's more for pick up orders, but it's still a drive through. And most are also Wing Streets. And if they are doing their lunch buffets, I would imagine you can pick up anything they may have ready to go from the drive through, too. Which is about as fast a food as you might want. And the lunch buffets are a better deal, anyway. Isn't that fast enough?
And after working in several Italian restaurants and pizza joints before, there's a lot of problems to work out to make it really fast. You have to top the pizzas when they are ordered. You can't leave them refridgerated and topped, ready to cook for very long, or they will sog out and fall apart. Then you have to cook it. Even the fastest conveyor belt convection ovens will take 6-8 minutes to fully cook a pizza, depending on the crust. How long is the line in the drive through now? 10 cars? And it isn't even boxed and cut up yet.
Then there is the noodle dishes which present a whole new set of prep, storage and cooking problems. You get the idea. And if there are any shortcuts, it will probably effect the food negatively. These same problems effect many different foods, obviously. Which is why your choices for fast food are so limited.
