Five Guys is the only fast food of its kind that I'll eat now. The design of the restaurant allows customers visual access to much of the kitchen and prep areas, so I can honestly attest to the cleanliness of the store, generally speaking, each time I visit. The burgers are delicious, and there are more options for burger toppings then can usually be found in other stores selling burgers. I can't rave enough about the french fries! I love that they're made from potatoes as one would make fries at home, were one not too lazy (that one would be me).
I really have no complaints about Five Guys. As I said, that's the only place where I'll go for a burger and fries.
