There is a fantastic service that allows us to order food online. It is called Yemeksepeti.com (something like food basket) where we can order food in almost every turkish city. Restaurants join this service and customers are allowed to order from their computers to every restaurant that serves in a given area. We can also choose different paying methods and usually the food comes to hour house in no more than half an hour, depending on the kind of restaurant and its situation.
Moreover, the web has an english version. However the translation of the products depends of every restaurant but some of them include pictures of every dish.
A great option if we are hungry but lazy.
