Take the stairway down beside the Aya Sofya garden gate to find this casually fashion-conscious cafe, popular with a young-professional crowd. It has acres of glass window and an ample lawn-terrace for nargile (₺45 to ₺200), both with wide views out across the bay. The menu covers Black Sea, Turkish, Mexican and Italian bases, plus steak and fresh fish. Or just stop by for an espresso.
It's 4km west of centre, just metres from Aya Sofya.
