I wonder if there would be a market for something that presented the user with a food-deliver-app type interface, but in actual fact is just interfacing with an API on the restaurant's behalf (in lieu of the restaurant having a custom delivery order page). Basically a middle man to replace restaurant's own custom ordering systems (which are often janky, and all act differently). The delivery would still be done by the restaurant's employees, but the service would handle billing the customer, building the UI, and so on. Such a service could charge a far lower fee to the restaurants, since they would not need to employ, ensure, etc. drivers. I doubt the customer would care either way, as long as the UI is just as convenient as the existing food delivery services.
