It's worth a trip up, the view is amazing. I wish I would have checked out one of the restaurants on the top as well. Great spot to take some amazing pictures of the city. The $4 trip for up and back was a little pricey, but hey what tourist attraction isn't expensive. They really need to ditch the exact change thing though. Fine if you want people to pay cash only, but in change only too, weird. But, why staff a both if you are going to send people to a change machine anyway? Guy at the booth was very grumpy.
