Personally, I think of Five Guys as overpriced fast food. Being a health freak, I get really queasy at the sight of the dripping grease, but I was willing to accept that fact because it is a "burgers and fries" place.
I thought their burgers were just okay, nothing to brag about. Fries were fresh, but just fries. I did enjoy the free peanuts though. I'm not a burgers and fries gal, so probably won't return here unless I really have that craving for their cajun fries. Yes, try their cajun fries...best thing there.
