I just found out that I am going to join a friend at the end of her business trip and spend the last week of November (25th-Dec. 1st) in Turkey. I have yet to do any planning/research into my travels, but am hoping to structure it all around food. Arriving and departing from Istanbul, but am expecting to only spend a day or two there. I'd really like to get out and see at least some part of the rest of the country. Does anyone have any suggestions of the must-have/must-sees for a couple of folks on a more moderate budget?
