Five guys makes a great burger. Same style you could make at home if you had the time and stuff and didn't mind a mess.
I give it three stars for two reasons, the price tag is simply too high for size and quality of the burgers. The fries are huge and I love the seasoning option, but they are always woefully undercooked floppy and greasy.
The free in she'll peanuts are just strange to me, and the shells end up all over everything giving the impression its dirtier than it really is.
If you're looking for a tasty burger and don't have time for a restaurant, give it a shot. Just not what I think it should be, especially given the hype it receives.
