Remember the cheerful burger joints from the 1950s? Even if you only saw those in movies, Five Guys Burgers and Fries will help you reminisce. From the red and white checked interior to the exceptionally cheerful staff, this burger place seems straight out of Happy Days. The burgers are made with 100 percent real beef, and the fries from fresh cut potatoes. Diners can help themselves to handfuls of peanuts as soon as they walk in the door. Rock 'n' roll music plays over the loud speaker, and the cooks take pleasure in their congenial exchange of "two patties down" and "six in the door!"
