Perhaps even better than the In-n-Out secret menu Cheese Fries, melted cheese douses crispy Five Guys french fries. For the dairy addict, this innovation may be what keeps you coming back for more – a mountain of cheese baked onto your fries – despite how good the burgers are. Sometimes they’ll make them for you for free, and sometimes they charge 50 cents, but the investment is worth it for the dedicated cheese fanatic. Give them a try next time you go!
