A group of 6 of us did the Protocol room. I have played 7-8 different escape rooms in my life (with varying success) and this was the best. When speaking with David the owner, he showed me the 3D printer he uses to create objects for the room.
These are the best, most creative rooms in London! I have done all of their rooms so far and highly recommend that you go here for the ultimate escape room experience. The staff is super friendly and helpful too. Custom work for a custom experience.
This Escape Room company is worth your time!
