Slaves of Spiegel serves as a delightful reminder that reading is not only an intellectual pursuit but a joyous indulgence. Imagine the universe under the exuberant rule of the Fat Men space pirates, who now find themselves in a peculiar dilemma. Having devoured every dish of interest, they are stricken with ennui, yearning for a new conquest. Their ruler, the illustrious Emperor Sargon—known as "Sargon the Fortunate, Sargon the Fantastic, Sargon the Fattest of the Fat"—commands a cosmic quest for culinary decadence.

He decrees that his band of buccaneers scour the galaxies in search of fast food maestros, chefs renowned for crafting the most outrageous junk food. The crème de la crème will be whisked away to the distant planet of Spiegel for a culinary showdown like no other—a contest to crown the ultimate artisan of audacious eats. Amidst this outlandish quest, the unlikely duo of Norman Bleistift and his employer Steve Nickelson, proprietor of the whimsical Magic Moscow restaurant in Hoboken, New Jersey, are drawn into the fray.
