5. Kat Restaurant

"Rooftop Dining in Cihangir 5.Kat (Floor 5), in Istanbul’s upscale Cihangir neighborhood, boasts a menu of gourmet cuisine and magnificent views of the Bosphorus in an elegant setting. The prices are a little more than what you pay elsewhere, but then there’s not many places in Istanbul where you can enjoy high-quality dishes such asoven-baked lamb shank, sea bass, and seafood linguine from a rooftop location. Dine here during the day for a buffet brunch and you’ll enjoy the sights and sounds of the Bosphorus, while the evenings are spectacular, with the lights of Istanbul twinkling in the distance. The prix-fixe menu is three courses, with local drinks included."
