ClueQuest: Revenge of the Sheep, London (England)

Bow to the Master! 

ClueQuest had an interesting take on Escape Rooms in that their theme was based on a secret agency run by a mouse named Mr. Q. It's hard to describe so here's an except from their site:

"Professor BlackSheep is back again to destroy mankind as we know it by turning us all into sheep! And this time he is not alone - he’s got an evil side-kick and together they have built a dangerous device: the SheepMutator."
