Mmmm... pie!
You've seen the Port-a-Diners, their color bringing a touch of something sweet to otherwise drab environments. In a way they are time capsules, each locking away a perfectly preserved slice of life before the Great War, before radiation, before things got difficult.
Difficult like operating a Port-a-Diner. And they are difficult, trying to deny it would be more artificial than the pie ingredients. So, it seems only just that the PERFECTly preserved pie contained within ought to live up to it's name, being nothing short of perfect.
What would make the Perfectly Preserved Pie perfect for you?
