Sky 100 is an indoors observation deck located in the 100th floor of ICC, the tallest skyscraper in Hong Kong. The ICC (International Commerce Centre) is located in the Kowloon side of HK. To get there, we took the MTR from Hong Kong station and alighted at Kowloon station and walked the long linkway all the way to ICC.
Admission prices are bit expensive but they offer senior citizen discounts. I'd say the 360 degree panoramic view of Hong Kong from up there was totally worth the price.
