Spent a rather profitable hour or so here on our way to Edmonton airport just over a week ago. Even though it was late on a Saturday afternoon there were plenty of free games to choose from and I had good success on 2 of my favourite ones (which made for a nice change)!
There was plenty of room to move around and people weren't bumping into your chair back as they passed by.
My only real complaint with this venue is the poor air quality as smoking is allowed in part of the building and that is not a self contained area. I just tried to stay as far away from that area and anyone who was smoking as I could.
