3.5 stars!
I've been here twice. Had Groupons to go with some friends. It was easy to make reservations online. It's a bit hard to find the place because it's situated above a cafe and it has a very narrow and steep staircase. It does seem a bit sketchy when you first arrive. There is a paid street parking on Yonge Street.
The rooms seem to be quite difficult to escape there. We picked the "easiest" one but still couldn't figure it out until we got extra time because the next group had not arrived yet. We had noticed that the clues weren't relevant to one another and they seemed very random, which made it more difficult to solve. The second time we went, we tried a medium difficulty room, and escaped with 5 seconds to go. The staff members are very friendly and helpful.
All in all, it was a good experience and now I'm hooked on escape rooms!
