There is not a lot of places in Toronto (or anywhere else maybe) that you can get that high to see the city. We went there first time during the day, it has an entrance fee but its not too expensive. Alot of kids, school classes and tourist, of course. Second time we booked a table with set menu for a dinner at sun set. It might seem expensive but then entrance is included and the resturant spins 360 degrees (very slow) while you have dinner. Worth a visit, qucik or for dinner!
Small insider tip: while walking around in toronto keep your eyes open for the CN tower, every now and then it pops up between buildnings and gives you great pictures.More
