Ah, is that the Djemaa al-Fnaa?  Nice.  Alas, the Khan has no snake charmers or storytellers, but it does have a fairly similar general atmosphere.  Both are far too touristy in the main sections for me.  But at the Khan, although most of the souq is the same as it ever was, there are several buildings that have been gutted inside and "renovated" into what amounts to mini shopping malls.  It's awful.

That said, the awful tourist kitch is only a few winding alleyways away from the real sections of the souq, which are much more appealing.  And even the main tourist section has some great stuff buried in amidst the plastic souvenir geegaws....
