<p><br /> The world's highest restaurant has opened its doors, located at a giddying height of over 400 metres above ground in the world's tallest skyscraper.<br /> </p><p><br /> Over 400 balloons were released into the air to mark the opening of Atmosphere, located on the 122nd floor of the Burj Khalifa in Dubai.<br /> </p><p><br /> The restaurant has a 180 degree view of the Dubai skyline, visible through floor-to-ceiling windows giving a floating sensation to those who choose to sit on the edge.<br /> </p><p><br /> Atmosphere's designer, Adam Tihany, said the interior was designed to take customers on a journey, like a "luxury yacht in the sky".<br /> </p><p><br /> But designing a restaurant at such high altitude was not without its challenges.<br /> </p><p><br /> "Some people were a bit apprehensive...would people be comfortable at that altitude, would it feel a little strange? So my desire was to create a very beautiful and almost a cave-like space that when you are up here, you feel safe, you feel elegant and luxurious, you feel sexy," Tihany said.<br /> </p><p><br /> Meanwhile, the executive chef at Atmosphere, Dwayne Cheer, said the menu was not fine dining, as might be expected of a restaurant that shares the same building as the Armani hotel and luxury residence of Burj Khalifa, but said it was "simple food done well".<br /> </p><p><br /> The average price for a starter at Atmosphere is around $50 while a main course will set guests back more than $90.<br /> </p>
