It is hard to identify exactly when the forgotten neck of Istanbul between Etiler and Arnavutköy became prime real estate. Not so long ago, overgrown green space alongside the road was interrupted by the occasional car wash and low-slung shanty; it was not so much a place as a road to other places. But now it seems this road is going places of its own. A private tennis club with a swimming pool shares a parking lot with Backyard, a café and restaurant with a big grassy yard filled with lounging parents and children wallowing in that rare Istanbul commodity: grass.
