> take a huge portion of the (like 30%) of the ticket price just for delivery. At least for restaurants which don't offer delivery themselves (which is the vast majority), the delivery service may be creating more than 30% of the value of the final product. "A meal delivered to me from any restaurant within about 3 miles" is often a different product than "A meal that I need to spend 20-50 minutes going to and coming back from." Although they're similar, they aren't always substitutes for one another. Obviously the adoption of delivery speaks for itself, but beyond that, I think if one just asked buyers how much of the value is provided by the delivery company, many or most would say over 30%. The target market does not consider it "just delivery."
