Caught the show at Navy Pier. These acrobats are incredible and put on a very good performance. This is the first cirque du soleil I've seen that was not pitch black. Their stage is underneath a tent top and it was a daylight show. We had 3rd row seats which was cool - but also a little scary. (I didn't sign up to catch someone if they fell!)
I've seen various cirque du soleils and I think one of the best was the water cirque at the Bellagio in Las Vegas (quite a few years back).
I also was entertained by 'Ovo' which I saw last year in Atlanta.
