ClueQuest
The longest-standing escape room in the UK, ClueQuest is based in King's Cross. They offer four different scenarios, where you can explore a spy-themed universe while trying to break free across a 60-minute session.
They also offer an outdoor experience, where you'll venture across the city in teams of two to eight people, solving mysteries as you go. Plus, there's even an option to take on one of their quests from the comfort of your own home.
