This is the 'Skylon' Revolving Dining Room and it has a Observation Deck on top. What a fabulous view. My husband and I really enjoyed our meal there, courtesy of Triple 'A'. We got back from Canada and our vacation time spent at Niagara Falls this Saturday past. In this picture, the yellow 'car' is an exterior glass enclosed elevator which you ride up to the top and what can I say about the view?? Breathtaking!!
