Shopping is always a good way to spend a rainy day and the Grand Bazaar has been the place for shopping in Istanbul since 1461. Originally a place where merchants from throughout the Ottoman Empire and the world beyond gathered to sell their merchandise, today it is more a gathering place for tourists. It gets a bad rap in most guidebooks for being touristy and tacky, but, while that is true, it is a fascinating place to visit. And, if you do want to shop, I think you could find just about anything you might want if you just look around long enough. (And the building is interesting too.)
