360 Chicago, previously known as John Hancock Observatory, has the best views of Chicago downtown and Lake Michigan compared to Willis tower (Sears Tower). Definitely buy tickets online or buy a CityPass since it is hard to predict the wait times in line for tickets. Parking is a pain in the downtown. Instead of shelling hundreds of dollars on parking, it is better to get a day pass from CTA or buy a hop on hop off bus rides or better yet walk if you can :)
Conveniently located in Magnificent mile, the observatory deck is in 94th floor of John Hancock Tower. And a ride in the elevator takes about a minute to the top and you can definitely feel your ears pop. Plenty of space to accommodate people at the top but wait for elevators is a bottle neck. A small cafe & bar at the observatory floor servers coffee, sandwiches, ice-cream and drinks. Gift shops are located at the top and the bottom floors.
The observatory deck is enclosed by glass walls on all sides. East, West, North and South views of Chicago and Lake Michigan are absolutely beautiful. East and South views covers downtown Chicago skyline and Navy Pier. West covers downtown Chicago and Chicago West side. North views cover the beaches, lakefront and beachside drive.
South side views has a new feature Tilt added to enhance the visitor's experience. A 7$ ticket purchased at the observatory deck, gets you access to the Tilt. This can accommodate 8 guests at a time and is around 10 minutes activity. The enclosure tilts forward by 30 degrees over Magnificent mile.
A 24$ ticket gets you Sun and Stars package where you can visit the observatory deck twice in 48 hrs. This is a great deal to view Chicago's night skyline and Navy Pier fire works every Wednesday and Saturday during Summer.
