Short story, but it hits it's marks and got offstage.
Well done. Eewww, pun not intended.
You aren't sure what the patrons and maitre'd are until a ways through: apocalyptic survivors in the ruins of a formerly great metropolis, zombies, something else?
At an apocalypse restaurant, being all upper crust in a ruined town.
The setting and action is weird, and disgusting, and delightful.
The set pieces are well described.
Will definitely be looking up more by this author.
