At Five Guys, fresh is key. The menu revolves around hand-cut french fries cooked in peanut oil, made to order from whole potatoes. Burgers are similarly crafted with a variety of toppings available, including free toppings such as lettuce, tomato, mayonnaise, ketchup, and mustard. Optional toppings like grilled onions, bacon, and A1 sauce come at an added cost. The "Little" burger is a smaller version, while the "Hamburger," "Cheeseburger," and "Bacon Cheeseburger" offer more substantial options.
Additional menu items include hot dogs, sandwiches, and salads. Drinks include soft drinks, milkshakes, and bottled water. Five Guys offers a unique experience with employees known as 'Shamrock Shakes,' which have become a seasonal specialty item that is only available during the months of February through August at participating locations.
