Patty Melt (Five Guys)
You should never have to choose between a grilled cheese sandwich and a burger, which is why Five Guys lets you (covertly) order them together. Just ask the person in charge for a grilled cheese with a hamburger patty, and then pick out all your toppings. You can even get multiple patties, if you have no fear or knowledge of coronary heart disease.
Gummy Bear Smoothie (Jamba Juice) Taking a page straight out of Haribo's playbook, Jamba Juice offers a non-official "Gummy Bear" smoothie that's as green as Pacino in the beginning of The Godfather. The blend of sherbets, peaches, milk, and lemonade is supposed to taste just like candy, though you could be drinking a very healthy kale shake for all the rest of the world knows.
