If you have visited Chicago before then you will recognize the distinct look of the Marina Towers.
This was taken from the office of Perkins and Will Architects on the 36th Floor of 330 N. Wabash. I had a fascinating tour of their offices guided by one of their architects. The views were stunning as the windows were floor to ceiling and as their office covers the entire floor they take in a 360 degree view of the city. Unfortunately I went first thing in the morning and the wonderful views over the river, lake and southern part of the city were killed by reflections.
