The bean in Chicago is well, a bean shaped mirror. You have to fight through the crowds to get a good picture. I took the kids and said it was a "park," so they were upset there were no swings. After arguing with them to help take nice photos, I told them to go ask the crazy guy talking to the pigeons if he would take them home for $20.
The fun part was all the wedding parties at the park trying to get the perfect shot.
