Right, but they're doing so without any kind of permission. They're either taking orders and not delivering them or in some cases taking them, buying the item from the restaurant and selling it to the end consumer. I would think that might require a different kind of license, if it is legal at all, because the restaurant doesn't have any contractual control over what happens to the food after it leaves the premises in terms of storage time, temperatures, etc. If the menus are outdated, the delivery service may not even know what's in the food.
