Christmas is not really celebrated in Turkey. But you can find some restaurants with Christmas dinner anyway. Here is a good list: http://www.timeoutistanbul.com/english/4967/festive_venues Also there is a restaurant called Molly's Restaurant around Taksim: http://www.tripadvisor.co.uk/Restaurant_Review-g293974-d1503815-Reviews-Molly_s_Cafe-Istanbul.html Another good option for you would be El Toro. It's around Taksim and the owner came from Spain years ago, so you can also have a nice conversation :)

you can choose any resturant but it must be in istanbul throad :). you can watch bogazici bridge...
