I haven't visited many shopping centers in Istanbul (to put it mildly), but Zorlu is the largest and most interesting one I have seen.
It has an excellent layout: at ground level, there is an open green space in the centre, flanked by air‑conditioned galleries (that is where the most upscale brands in the mall are located).
Inside the building, you can find products for every audience, every visitor, everyone who got there - there is Adidas, Nike, H&M, and plenty more. There is a cinema too, though I didn't go in.
In the centre stands a magnificent two‑level Apple Store, very bright and stylish.
There is a fairly large food court plus several restaurants. Among the global brands at the food court, you'll find McDonald's, Burger King, and Popeye's. If you are looking for a lighter bite, take a look at the Green Salads chain - their salads are generous and packed with vegetables.
We got here by taxi; the trip from Fatih (almost from Hagia Sophia) took about 30 minutes, but it was a weekend. On weekdays, given Istanbul's traffic, it will clearly take longer.
Taxis line up outside the mall exit: there is a separate row for "regular" taxis and another one for minivans.
It is a beautiful, convenient, and green shopping centre; in my view, the most pleasant and interesting one in Istanbul.
