As far as I know Dubai has only one totating restaurant which is at the top of the Hyatt Regency hotel,oh! but you can't beleive, at night if you view the city from here, wow! fabulous!! I got a chance once. The Hyatt Regency hotel is one of the most popular
dining locations for all the visitors and most of the visitors eat here. And I think it takes more than 2 hours to rotate once, but offers wonderful views of the entire city and you can get food from all over the world.
