They are almost a 100% american.
They are HUGE.
I don't know if this is an interesting topic but maybe it is. I have been to two different malls so far. They are both very similar in terms of their architecture, shops, food, activities and all malls have only been constructed very recently. I should note that the majority can only be accessed by car or taxi.
Clothing- and beautywise you would encounter American well-known brands such as GAP, QuickSilver, Forever21, Nike and Victoria's Secret to name a few. The food-court is western too with a wide variety of different fastfood to choose from. Above of that they offer activities for children and adults alike, for instance Lasertag.
