Food is very cheap and good in Istanbul. You can just walk into any restaurant, order something and it's going to be excellent. We didn't care for the food in Cappadocia. Cappadocia is really ancient Anatolia and the food is really of peasant quality. We decided not to bring home any cookbooks which is a good thing. We've got cookbooks from Morocco, from Egypt.... we've not cooked a thing from these books.
