Rating 2 stars mainly due to the deceptive payment model. They advertise that the ticket is 95 AED, but 50 of that 95 can be spent at the café above. However, at that café, the water costs ≈30 AED, and the cheapest food options start at 50.
Additionally, the windows were very dirty, which is unacceptable for an "observation deck".
From there you can enjoy stunning views of the city and the bay. When I reached the height, I immediately wanted to take a bunch of photos. The sunset was especially beautiful — the sky was painted in incredible colors, and it looked just gorgeous.
The staff at the site was friendly and always ready to help. I also liked the information signs that explained which buildings were visible from this height.
The only drawback is that some windows were slightly fogged up, and this prevented a good viewing, but it did not spoil the overall impression.
In general, I recommend visiting this place if you are in Abu Dhabi! This is a great way to see the city from a height and enjoy its beauty.
