The view of the downtown Chicago skyline from the John Hancock Center is breathtaking. If you go to the observatory, I believe it costs about $20. You do get the full view from around the whole building, but for about the same, it’s more fun to have cocktails and treats at the Signature Lounge on the 96th floor of the Hancock Center. KM and I went just before sunset at it was the perfect timing.
If you liked the bathroom at the Palm Court at the Drake, the ones here are not to be missed. The picture is kinda crappy (no pun intended) but you can see that it probably has the best view of any bathroom.
