Loved for its juicy, just-cooked burgers and crunchy, skin-on fries, Five Guys has something of a cult following. The cheapest deal is the vegetarian option. The veggie sandwich, with lettuce, tomatoes, grilled onions, mushrooms, and green peppers, all crammed in a soft, toasted sesame seed bun, is the cheapest option at around $5.30, depending on where you are. Here’s another secret: Five Guys' little fries are priced at around $4.99, and, despite the name, the portion is huge.
