Sadly in some areas Uber eats and such have caused mom n pop delivery to disappear. There's a chain in Los Angeles, Lucifer's Pizza, which no longer offers delivery. If you call them up they tell you to use an app to order.
Papa John's in my area transparently subs delivery out to doordash now, and the experience is terrible. The drivers don't get tips (unless I happen to have cash, which I never do) and the pizzas arrive cold (presumably because they're trying to batch a lot of pizzas up in a single trip). I've given up on it.
