The much-acclaimed CN Tower is Toronto's most recognizeable and famous feature, and was the world's tallest free-standing structure until the Burj Dubai surpassed it in September of 2007. It is still the tallest free-standing structure in the Americas. At a dizzying 553 m high a visit is worth it for the view of the city alone. Visitors can look out from behind glass windows or go to an outside observing area to look through a metal screen. It attracts large numbers of tourists; best times are weekdays in the morning. Visitors can jump up and down on the thick glass floor in parts of the observatory the view from the floor downward essentially shows the base of the tower. 360, the revolving restaurant, is located in the main deck, but isn't particularly renowned. Restaurant diners with reservations can avoid the queues for the observatory, and at night the lights from distant Rochester, New York are visible over the lake. Approx. $20 budget or $28 to go up.City Hall and Nathan Phillips Square
