The entrance to the Burj Khalifa observation deck begins here. We went up to 124-125 floors, there is also a ticket to the 148th floor for about twice as much. The queues are very long, although they move fast. It took about an hour from the beginning of the queue to the entrance to the observation deck. The queue for the descent is about 15 minutes. It seems to me that the view is not worth it, but they put a check mark on the list for visiting Dubai
