What days of the week is the spice market open and what are the hours of operation.
I'm not sure of the exact hours, but if you are planning on going during normal business times, it should be open. We were there around 11AM and it was humming.
When I was there a few years ago, it was closed on Sunday, but I recently read that it is now open on that day. Definitely don't miss a trip there - the smell alone is intoxicating! And bring your camera - it's a feast of color!
See Page 45 in Rick Steves Istanbul guide book (4th Ed) for lots of information on the Spice Market.
I do not know why my post has a lot of %&$ in it but all I was trying to do was put the 4th Edition in brackets.
