Five Guys is an American fast casual restaurant chain focused on hamburgers, hot dogs, and French fries. Now, 30 years after Five Guys first opened, there are almost 1,500 locations worldwide and another 1,500 units in development. Five Guys continues to receive generous media attention and has grown a cult-like following around the world. We only use fresh ground beef. We only use peanut oil, and there are no freezers in Five Guys locations, just coolers.
