Rapid tissue cloning from donated cells + vat-grown flesh as food-products = “My God… I’m delicious!”
They’d called the restaurant Eat My Ass. And the staff handed out FAQ sheets as to why they did it.
Fast-tissue cloning worked best on the muscles of the gluteus maximus. Which, in the kitchen/laboratory, became the best well-marbled meat individually tailored for each customer.
They had a wide variety of dishes that, technically, were veganism in its purest form. No animal had to suffer, because the only protein came from the customers themselves.
And everyone who ate there had nothing but praise for the food.
The only drawback?
Everything was a cut of rump.
