Without any doubt, a fast food joint that is loved by the majority of the heavier people I know would be a perfect fit. People who are fit and health conscience sneak them when they are not with their partners. That would be White Castle. The joint would be jammed around the clock!
If you don't know what White Castle is please take my word for it to die for is the correct thing to say about the food. Hamburgers are commonly known as Sliders!
Harold's would be my second choice, Pinball Wizard is a Culinary Genius. A combo of both restaurants would be great.
