The ArcelorMittal Orbit at the Olympic Park

We went to Westfield shopping centre for a bit shopping and went to the cinema while we were there.  We saw Tomorrowland, which we all enjoyed.  While we were there I took this blip of the ArcelorMittal Orbit at the Queen Elizabeth Olympic Park.  We haven't been up it yet as it seems quite expensive for what it is.  If anyone has been up there I would be interested in your comments.
