Has Anyone Been INSIDE the St.Louis Arch? What does it look like?

We are going to St.Louis And I want An Idea What the inside of the arch looks like.Has Anyone Been INSIDE the St.Louis Arch? What does it look like?
I worked there as a tour guide. It's awesome if you go get there early and enjoy. It's only $10 for adults, the prices go down from there for children, elderly, etc. there are always movies showing inside the arch also. Other than that if you or anyone in you family have any more questions from some who worked there, you can email me. bye:)Has Anyone Been INSIDE the St.Louis Arch? What does it look like?
