"Here are some more traditional but fancy suggestions; Feriye Lokantası (Ortaköy), Zeyrekhane (historic peninsula), Nar Lokanta (close to the Grand Bazar and has Armaggan, which is a design shop), X Restaurant (on top of the Istanbul Culture and Art Foundation) and Mikla Restaurant (on top of the Marmara Pera Hotel)."
