You never know when you try something new in a city you've never been to before. Right after we were done my kids wanted to forgo lunch and do another one.
It was a little hard to find but just look for the small blue key sign.
The room was tons of fun. Hard enough that we didn't succeed in finding all the clues but easy enough that we didn't give up.
Staff was very helpful. They even suggested a tasty place for lunch.
If we come back to Montreal we are definitely doing another room.
