I was taken here by my girlfriend a little while ago - we had a good time but both found that it was WAY too crowded in the arcade area. She was trying to play ski-ball and would constantly pull back for her swing and hit someone in the leg, and she was TRYING to not hit people. Something else we found kind of sketchy was that we'd see large groups of drunk/drinking older guys around little kids playing the same games, just seems really weird to me.
The idea of this place is great - food with an arcade for adults/kids together. Some games pay out WAY better than others though, so i found that to be unbalanced (I won a 1000 point jackpot for 2 credits on a skill based game that I completed at almost 100% more than once, and actually got the max score twice while I was there, whereas some other games you are paying 5 or 6 credits for and maybe snagging 30 points if you're lucky).
Overall, we will go again, but they really need to expand the space between games in the arcade area - we get that you're trying to cram as much in as possible and that it probably cost an arm and a leg for the space right near the CN tower, and that the downtown core has so many people its hard to breathe sometimes, but please try to keep in mind that people need more than a foot of space to play the games. Not to mention that at least 50% of the bar/eating area was totally empty at the time.
