Maslak is the new business center of modern Istanbul. You can notice the high rise buildings in the road between Zincirlikuyu and Maslak. Most of the headquarters of multinationals (Unilever, Roche), banks (Akbank, Isbank, YKB, Garanti Bank) and large local conglomerates (Sabanci Holding, Eczacibasi Holding) are here. So this area is mostly for business travalers.
