If you have more time, you can explore some of the other neighborhoods in Istanbul such as Bebek, Nisantasi and Karakoy. For those with less time, reduce a day from your itinerary. You may also want to check out some of the famous landmarks such as the Hagia Sophia, the Blue Mosque, and the Topkapi Palace. Keep in mind that some restaurants and activities may close on public holidays or weekends, so double-check before reservation.
