The John Hancock building does have an observatory which allows a 360° view of the city, up to four states, and Chicago's only open-air SkyWalk with paid admission. I felt my money was best suited to just head to the Signature Lounge on the 96th and spend it on drinks, getting tipsy while still enjoying the spectacular views. I opted for the Chicago Martini which was very delicious but a little too sweet for my taste. My boyfriend who came with me got the "Chicago’s Best” Sidecar Martini which he seemed to enjoy and a Great Lakes Porter. The drinks are a bit pricey but they are well made and strong so it's definitely worth the price.
It may very well be a great experience to head to the observatory, but you are definitely in for a good time and amazing experience visiting the lounge instead!
