Everyone knows this Duty free! There is even a sports ground in bulk, in general there is everything you need. As an example, glasses are 200 dollars cheaper than in the Dubai Mall, namely Prada.
Business halls are not bad, but you can't really sleep anywhere, you won't lie down, so far the plaza premium lounge is the most liked of all, good showers, clean, good kitchen, there is a smoking room in the bar!
Well, Dubai kids fries are always on top!!!! Here you can definitely find what your heart desires, and the prices are affordable in principle compared to others
