What fast food franchise would you choose to open and why?

If you were to start a fast food franchise which one would you choose to open? And is there a reason why you picked it?

(examples: McDonalds, Burger King, Nandos, Subway etc..)

I really want to start up a Nandos, ideally have it built nextdoor to where I am living! One great thing about owning one would mean free food. lol :P
