5 Guys is a damn good burger, but their fries are horrible. I was gonna put them - but the question was about fast food. Red Robin burgers are just ok - though Ruth'll gnaw your leg off for their fries. Best flavored burger I've had at a restraunt I've had was a local place called Jeremy's - but their medium well was medium rare, so a little on the underdone side for me to rank as best burger overall.
I used to like Red Robin and yeah the endless steak fries is cool, do they still do that? Haven't eaten there in at least 6 or 7 years.
