The shopping center is the most ordinary - there are many shops, but it is easy to get from Sultanahmet and Taksim. Discounts need to be caught, there is no Nike and H&M (( but a bunch of others. Large food court
There are a lot of mass and brand markets, a good choice, for foreigners there is an opportunity to use free Wi-Fi. After shopping, you can also drink coffee there in the coffee shop.
A very large shopping center, many different shops, a food court, somewhat resembles our Mega. I advise you to go here if you need different brands of clothing
