Absolutely incredible! The Allo Montreal exhibit was cute; great to show kids about the evolution of telephones. The museum layout could be confusing but they explain it to you at the counter and you get a map. My favourite part of the museum is the glass over top of the archaeological remains; LOVED that. The sewer is very cool as well; I appreciate that you are actually standing on a part of history and it is not replicated. Wonderful way to spend an afternoon.
