How I Did It: Jerry Murrell, Five Guys Burgers and Fries

From Inc:

The magic to our hamburgers is quality control. We toast our buns on a grill — a bun toaster is faster, cheaper, and toasts more evenly, but it doesn’t give you that caramelized taste. Our beef is 80 percent lean, never frozen, and our plants are so clean, you could eat off the floor. The burgers are made to order — you can choose from 17 toppings. That’s why we can’t do drive-throughs — it takes too long. We had a sign: “If you’re in a hurry, there are a lot of really good hamburger places within a short distance from here.” People thought I was nuts. But the customers appreciated it.
