Putting a third party between you and your customers when you are selling a highly perishable product in a highly competitive market is crazy risky. One area I have thought might work is if these food delivery services act as the seller and take responsibility for quality. You could have a DoorDash sell the food and outsource the production to the restaurants. The customer would not know where the meal came from and any quality issues would be on the DoorDash services plate (sorry for the pun).
