This room represents a new concept in the Dungeon Catering industry.
Staffed infernally, but the impish employees need never interact with a bunch of surly adventurers, as all refreshments are dispensed in self-service coin-op cubicles.
Adventurers can be assured that they can get food, healing and other items commensurate with their ability, as an on-premise “refiner” is available for use by staff.
Truly, this is the future of vending!
