The Green Jello has been adequately explained, as has the Utah version of the pastrami burger. That's something I'd like to address, though. Utah is one place you can come to and actually find some specialized fast food that is worth sampling (I'm sure others have similar things but I just wanted to brag).
Crown Burger. Back in the 1970s a Greek immigrant started a burger joint that served pastrami burgers, steak sandwiches, barbequed pork sandwiches and other items not found in the usual chains. When an Arab mogul built a business tower across the street he wanted a parking lot, and Crown Burger disappeared.
Several months later it was back, less than a block away. I got the opportunity to ask the owner what had happened, and he said "Oh, their offer was too good to argue with. So good, in fact, that I was able to open this new restaurant and two new ones, plus loan money to my cousins for their own businesses!"
So now we have three Crown Burgers, Atlantis Burgers, Apollo Burgers, and Burger Palace, all serving pretty much the same fare. And it's good.
