Five Guys is kind of the dive of burger joints. They have a simple menu of greasy burger and fry like items. It's a very east coast type place. Overall though, I give it a low rating because it just shouldn't be in your burger rotation. Between In n Out, The Habit, Fuddruckers, any local bar and even jack in the box your need for a random hamburger should really be well covered. There's even the upscale fast food burger now in places like Burger 21, just no real reason for Five Guys since it falls behind all of them in value.
On the positive, nice people in the place, and this location is unusually well kept up and clean. Hit one in Brooklyn and you'll see what I mean.
