Phone is the only method that supports all pizza places and prevents any barrier to ordering. It is the best method by default.
I've lived all over the USA, and I like pizza. In big cities, the closest pizza place is not a franchise. In small towns, often no pizza place is listed on an online service, the closest pizza place is literally a gas station, nobody takes credit cards, and delivery makes no sense. People in the suburbs are the only ones whose closest pizza place is a franchise with an app.
I have run into a slew of tech problems when trying to order online. Often I am not ordering from a chain, so I have to either walk through some bizarro custom website that doesn't work half the time, or I have to call anyway. If I want a deal, I'll look online, but I make the order by phone and pay at pick-up. The phone is the only thing that always works. Speaking my order is literally faster than clicking through a form. Even if you're deaf or blind, you can order pizza over the phone without issue.
And besides all of that, "ordering services" (Slice, GrubHub, Uber Eats, Doordash, etc) are actively detrimental to small business. Because people aren't calling in and ordering and are instead trusting these websites' listings (that the business owners did not list), the customer doesn't get their order or it's delayed or screwed up, and then they leave a negative review for the business on Yelp/Google, even though it's not the business's fault. More people should order over the phone, if only to ensure they actually get what they want, and how long it will take before they order.
I agree with you wholeheartedly that phone ordering is the best method, and I use it myself most of the time. It's always been the best method except during the busiest takeout periods at the busiest restaurants.
I just wanted to point out one nitpick, when you mentioned this: "Even if you're deaf or blind, you can order pizza over the phone without issue."
That is true, but that doesn't mean that online ordering systems cannot help people with disabilities. My brother does not have to live alone, but if he did, he is mute and has trouble using a speaking device. An app would be far easier for him than a phone call. In other words, accessibility requires both systems, not one or the other.
