The skydeck was amazing. I went on a night that was a bit cloudy so I wasn't able to see much past the water and out of the city - but the view of Chicago was amazing. I was up there while the sun was setting was was beautiful and also gave me a chance to see the view before dark and after dark when all the city lights were on! It was beautiful and for a decent price too! Just bring some gum to chew on when going up the elevator because your ears will pop! It is far worth it though!
