Or to put it more crudely: If your aunt had balls, she'd be your uncle.
I doubt it; I doubt many would do that at all. In some situations corporate fast-food joints do take reservations (White Castle on Valentine's Day evening is the only example I can think of at the moment) but in those situations they are cashing in on people considering it a novelty. The novelty drives demand to levels that it otherwise never achieves.
If there were only a single Chipotle in NYC, there would almost certainly not be enough demand to require a reservation system (and if they used one anyway, their business would surely suffer). Perhaps you would be willing to call in a reservation for Chipotle, but one person calling in reservations for fast-food isn't going to sustain a business.
Basically people will especially go out and get the McRib when it "comes back" and then get tired of it.
If McDonalds was limited to only one location, there would almost certainly be long lines, waitlists, and reservations. The ubiquity of McDonalds, and the fact that they can meet demand enough so that no one needs to wait more than a few minutes contributes to the luxury of not having to wait for a Big Mac.
You essentially need a completely new staff--including a completely new creative staff. This is important, and a large part of why most chefs who own multiple restaurants generally have fairly diverse properties that present different menus. But diversification still requires wheelbarrows of money; "the fastest way to make half a million dollars is to start a restaurant with a million" probably applies even more acutely to opening more than one.
