The Grand Bazaar, also called ‘Covered Bazaar’ in Turkish is one of the world’s largest and oldest covered markets in the world. There are 61 covered streets and over 3,000 shops. About 90 million enter the halls every year, the world’s most visited place (http://www.travelandleisure.com/slideshows/worlds-most-visited-tourist-attractions/2)
We came on a slow day, fortunately. The place is overwhelming just in terms of the sheer number of shops. Much of it you could buy anywhere, probably most of it. I have no idea if the deals are good. Just being there again was enough for me.
