i love sushi at www.swissotel.com.tr in istanbul and i especially recommend GAJA ROOF sushi restaurant, japanese and turkish chefs are working together - also you can prefer to eat in your room , although you have to wait a little at dinner time if you choose this way... it is a good idea to make a reservation ... hand rolls and nigiris are amazing ! take a look at their menu : /www.swissotel.com.tr/istanbul/pdf/Gaja%20Sushi%20Menü.pdf
