So I came here with my husband and 3 kids. The sign was really hard to find. We even asked a couple of people and no one knew wee it was. Finally we found it on the right side of the GoodWill and down the side walk which doors look creepy.
So walking inside it's really nice. There is an area too the side for shots and coats. Than you sign in. It's a little pricy for the side but I will admits it's really clean for a kids place. If out want for the Groupon I wouldn't have come.
The kids really liked both sides of the pay areas and the upper balloon room was the best for them.
Over all I would recommend going here if your in the area and want to tire out the kids. It is worth it. There are places cheaper in Mississauga but the extra drive had good results.
