Five Guys serves up much better than average fast food burgers, but if you grew up on In-N-Out you'll still be an In-N-Out fan after visiting Five Guys. I suspect if your from the East and grew up on Five Guys, you still prefer them to In-N-Out. That being said, the two burger joints are on par with each other. I prefer the fries at In-N-Out, but like the topping selection at Five Guys better (no secret menu required).
