It's ok bit not really worth $17 or even the time as there are no spectacular views to see from here. I may be biased since I've been to most of the tallest structures in the world sand this can not compete some of the world class locations
The mountains are too far away to view and the city geography is too flat to give you the wow feeling.
If you're an avid world traveler then this will be disappointing, for other it might be ok for some and others might find it great depending on what other places you've seen before
