This chic neighborhood by the Bosphorus was actually a residential one and with time it became more and more popular with cafés and restaurant.
This is where you can find good fish, ice cream, waffle, have drinks overlooking one of the nicest little bays on water, watch the private boats docked close to the shore, have your cup of Turkish coffee at Bebek Kahvesi which is one of the oldest establishments serving all sorts of istanbulites including the journalists and actors.
Breakfast at Mangerie with delicious jams and cheese overlooking the Bosphorus from the fifth floor of an apartment building is one of the delights of any weekend. There are various spots where you can sip your cocktail and people watch or enjoy the view of the Bosphorus.
One of the local delights in Bebek is the smashed almond, you can taste some at Meşhur Bebek Badem Ezmesi.
Starbucks also has a branch in Bebek, a serious candidate to be the Starbucks with the best view in the world!
