aka: Kashgar
The Sunday market happens every day. The only thing different on Sunday is the livestock.
In my opinion, Kashgar has become too easy for westerners to get to. It's become corrupted by the tourism industry. Those going to see authenticity won't be disappointed though. Just expect to see lots of Lonely Planet kids hanging around.
