You must not have many good burger places where you live. 5 Guys burgers are good, but IMHO Freddies's (http://www.freddysfrozencustard.com/) and SmashBurger (http://www.smashburger.com/) are both way better than 5 Guys.
A key reason for their success is this ability to retain the local burger feeling, while still being able to franchise quickly.
I actually like Five Guys, their Cajun-seasoned fries are amazing. There's also Ray's Hell-Burger, Foster's Grille, Tuskie's (amazing lamb burger), and others in Alexandria, Arlington, and DC.
