it's well worth the 5 bucks to do this, you can walk all the way around the floor so you can see in any direction. if you look carfully there is a falcon that nests on a ledge I think it's to the north side of the building (a seasonal attraction). Great for anyone thats not terrified of heights!

The view is just amazing!
You can see the whole city of Seattle, the Space Needle even looks small from there.
And... it's way cheaper to get up there than to the Space Needle.

Loved friendliness, and loved the panaramic views. Like looking at other buildings in skyline.
