Beautiful view of the city. Access is through the mall. There is a bar, quite expensive, but you can also go up just to take pictures.

Once we found the entance to the ION Sky we spend half an hour or so enjoying the impressive panoramic views from the vantage point. There is also a restaurant up on the viewing area but this was not.

Great view of Singapore, even though the air wasn't too clean that day. No charge to get to Level 55, not especially crowded
