A must-visit for any hockey fan. Most of the museum is filled with player memorabilia and stories attached to them. There is an interactive zone which is pretty fun, people taking shots and blocking them from a computer screen. It's all fine and loses some sheen until you get to the trophy room with all of the famous trophies headlined by the Stanley Cup. You can touch it as much as you want, which is pretty wild.
I would only recommend to hockey fans b/c if you bring someone not interested in sports or even hockey, they will almost definitely get bored and ask to leave early. I went myself and spent about an hour and a half.
