Heart Attack Grill. The Theme? Fast food is going to kill you.
...I'm serious, that's the theme >.> The service girls are nurses, your order is a paper tag around the wrist like a patient tag, and the food has medical themed names, like the Quadrouple Bypass Burger, and Flatliner Fries. Order the former, and they call an Ambulance just in case. You also get taken out in a wheelchair.
