So my group played the Ancient Mystery room, which is by reputation their best room. I actually thought the room was very good. I'd give it a three and a half if I could.
The room itself in terms of difficulty, logic, and theme was very good (4.5/5)
The location is awful. The facility itself is good, but unless you live on the West End getting there is a pain (it's on the far end of Mississauga).
That in itself wouldn't be so bad, but it's priced itself into the upper echelon of escape rooms. With all discounts available it still came to over $22 per person for a 45 minute game! This makes it one of the most expensive facilities on a per minute basis in the entire GTA and since I can't imagine the rent being comparable to the downtown, midtown or even uptown facilities I brought the review down from a four to a three.
Don't get me wrong, you'll have a very good time, but unless you're in Mississauga to start with you can find better, cheaper, more centrally located escape games.
