I was recently in Montreal on business and got a chance to check out the Amusement 2000 arcade.

This arcade is located on Rue St. Michelle, which is something like Sunset Blvd in LA, but much colder and with a lot more French signage. Anyway, this place was really great. The highlights for me included a wall of brand new Street Fighter 4 machines, the most recent OutRun (not sure what the name was), Terminator Salvation, and the Iron Man and Avatar pinballs. All the machines were in excellent condition. If you're in Montreal you really should have a lot of other amazing things to be doing with your time, but let's say you end up on Rue St. Michelle and are trying to get rid of your Canadian money before your flight home. YOu could do worse than checking out Amusement 2000.
