I was there for a private event, so this review may or may not be representative of non-private events, food, etc.
The view is definitely impressive. Many cities have a revolving restaurant/bar like this, and the reason is simple: They are unique and offer views that non-revolving restaurants don't and can't.
I would love to give this place five stars except:
1) It's not as tall as many other revolving restaurants. If I recall, it's only around 25 floors high.
2) The food was kind of meh, but it could be what our event planner ordered.
