Burj kalifa is the tallest man made structure ever built.with amazing look.....It was wonderful experience.....First of all we gone @ the top....but i reached only @ the 125th floor,there is 163 floor. View from there was wonderfulll....we took lot of photos and videos....Then we came back to ground floor, Then we visited aquarium in the dubai mall....Its a huge aquarium with lacks of fishes and hundreds of species....we gone under the aquarium through a glass tunnel watching fishes above my head... then above the aquarium in a boat feeding them....But i didn't go into the aquarium for diving....It was altogether one of my best memorable day.....
