Sure its ultra touristy and pricey ($35) but its worth the visit. Perfect to check out after an event at the Rogers Centre or Air Canada arena if your in town. The main observation deck has two levels, including a glass floor and a 360 degree outdoor deck (the fresh air is wonderful) and a dining cafe. The view is fantastic and as a visitor, I realized how big Toronto is.
But save your money - don't bother with the Skypod (an extra $12). Sure its "cool" to say that you went up 1,447 feet but the view is exactly the same, its not very big and its hot & stuffy up there.
