What an amazing city. I'll definitely be back and also visit the interior of Turkey. On the last day we went to the "new" section of the city - still in Europe but the Asian side easily viewed across the water (see image looking at Asia). We also took a little walk on the main drag in the new part of town, starting in Taksim -- well, starting with a tram ride then the funicular (drawn on rails by a cable up a steep hill). See the crowds that walk this shopping street, filled with tons of US store brands from Burger King to the Gap. In the old town we saw this guy selling pidgeon feed -- made us break out in song..."feed the birds, tuppence a bag..."
Off to Athens!
