This is one of the biggest malls on the Asian side of Istanbul, located in Atasehir, a rather new settlement area which has developed immensely in a few years.
There are all kind of shops, from spice shops to boutiques, from bookstores to shops selling electrical goods, there are almost all the brands that you may be looking for plus a food court and other nice restaurants, cinemas, hairdressers etc. When we were there, they also had a market for local products for one week. There is also a supermarket, Carrefour. The car park is quite large and quite convenient as well.
