Mark and I chose to have the reception at The Mid America Club downtown Chicago in the Aon Center--- such amazing location, right by Millennium Park and the water. It has 360 degree views of the skyline, and lots of space.
We are SO excited about the location and while it isn't the outdoor wedding Tina dreamed of (Mark is too practical/realistic about Chicago weather), its a really neat venue and the best location we could ask for!
Here is one of the views:
