I refuse to vote just for this reason. It would be comparable to creating a poll asking who the best baseball player of all time is, and leaving Babe Ruth off the list. For those of you that are not familiar with In n Out, that's all they do. When you get there, there is no need to stare at the menu for 15 minutes wondering what to order. They make a hamburger or a cheeseburger. That's it. The waiting lines to get through the drive through are always 10+ cars deep, whereas many other places you can zip right through with no wait. If you want a chicken sandwich, go somewhere else. You won't get one at In n Out. In n Out, the Babe Ruth of burgers. Same at 5 Guys. Despite my recently-acquired love for Five Guys, I'm obligated to point out that they also serve hot dogs at many locations, as well as grilled cheese and veggie sandwiches. I'd never eat one myself (well, maybe a grilled cheese), but they do have other things besides burgers. That's true for the Five Guys close to me. They have everything you mentioned.
