The Cloud 9 is one of the most amazing restaurant-bars in Shanghai. If you visit this Chinese city I recommend you do not leave without having visited it.
The restaurant is located on the 87th floor of the Jin Mao Tower, the second tallest building in China and the sixth tallest in the world at almost 500 meters high. It belongs to the Grand Hyatt Hotel, one of the highest in the world, and occupies floors 53 to 87 of this skyscraper.
You do not need to be a guest at the hotel in order to visit the restaurant. All you have to do is take the elevator to the 87th floor. It is a little hard to find if you have not been there before, so you should ask the building's staff for floor 87 or Cloud 9.
