Kick-Ass Fast-Food chains that are regional

Tommy's: If you've never been to a Tommy's, then I feel for you. Tommy's is a burger joint in the LA area that kicks ass above and beyond the call of grub.  To give you an idea of the place, the menu states that everything comes with  chili on it, unless requested. The chili is this creepy glob of rapture that is let cool congeals into a rather firm mass. Best post-bar food ever.

So, what other kinda local chains are awesome?
