Check out how successful Dick’s is in Washington. They have so many locations now. Their first location was Wallingford, Seattle. It’s about a 1 mile walk from the U district, where a lot of the college kids hang out. Now, Dick’s has a location in most major districts of Seattle, mostly around bars, and even outside of Seattle. They are cheap ($2.50 for a cheeseburger) and super fast because they don’t do customizations with a limited menu. Mostly window only walk up pick up, no dine in (except for the one outside the hockey stadium, but it’s standing only).

You’ve got the right idea.
