The area where this hotel is located is called Ortaköy and there are plenty of great places to eat there, right on the embankment near the hotel. I stayed for a night once and the hotel open-air breakfast was fantastic, so don't try to save on it (they won't recognize your Gold status and give you any perks on the F&F rate, you'll have to pay).

From the Ortaköy Ferry Station there is regular service to Kuzguncuk across the Bosphorus where you can enjoy the famous Ismet Baba Restaurant with great views over the water. Or you can stay in Ortaköy, walk uphill to Yildiz Park and have dinner at the atmospheric Malta Kiosk.
