I've lived in a city of 50k people and smaller, and in various suburbs (of major cities) and ALWAYS had a collection of delivery menus in a bag next to the junk drawer. I don't think I've even lived anywhere that didn't have a reasonable amount of delivery. That's not to say such places aren't common... just that "unique to NYC" certainly doesn't describe it.
