Thanks for the info.
The locals are a little reluctant to discuss "knock offs." The mall has changed a bit and the police have cracked down, but its still fun. Good thing we had a fold up bag along. Of course we could have bought a nice one in the mall, but didn't want the 10 minute negotiation.

I'm in Shanghai for a few days and would like to go to the shopping mall with the knock offs etc. I recall it being on Nanjing Rd., but don't remember the number. Any ideas?
