I recently went to the mall for a burrito (it's very hard to find good Mexican food in Cairo) and got lost for most of the time I was there and the directory doesn't help at all. The mall has more than just floors, it has phases and atriums. I have no idea what that means. It is a silly place.
City Stars in a nutshell: Two Timberland stores and one of them is located in Phase 2, 4th Floor, Shop No. 4205. They have so much space, they've run out of stores.
One of the most bizarre parts of City Stars is its elevators. You press the button for what floor you want before you get on it. This gets very confusing when many people have hit all the buttons and you have no idea if the elevator you're about to take is going up or down.
