the 5-guys Hype
5 Guys makes an excellent but not epic hamburger. What makes them so special is that you can get a huge variety of condiments on them, most free, and some for a reasonable upcharge. The more you put on it, the better it gets, but it becomes a sloppy avalanche to eat.
But then the truly amazing thing is superb french fries that they are extraordinarily generous with. Bad news if you are on a diet.
However, that may be the Southern Strategy, it may be different in NJ.
