I am not an underground expert, but the times I have been down there I noticed four things about it.

1. There were hardly any restaurants or shops there

2. The lack of people down there but surprisingly when I went up to street level afterwards there was a lot of people(but the weather was really nice that day).

3. How cool it was.

4. How amazingly convenient it would be to use on a rainy, snowy, or really cold day.

I am probably in the minority on this on OKCTalk, but I would like to see it eventually expanded and I would also love to see new artwork on the walls down there. The lighting is really nice in some spots. Others, not so much.
