They are the best fast-food burger. Their key to success is

Simple menu - 2 hamburger choices, fries, drinks, and shake. That's it. Just like an old hamburger joint.
No advertising - no need to advertise as a quality product doesn't need to. That money is used to pay better salaries and use better quality products for the burgers.

I like the presentation. It is one of the few fast-food burgers that when presented to you, actually looks like it does in the picture. You don't need to peel back the bun to see what's inside. It's all right there staring at you.
