Hey ter,
My experience is that you gotta do some homework here and in HK as well. Tsim Sha Tsui and Mongkok are the 2 places to go.
From my own experience, TST is more like SLS. Heard a foreigner arguing with a shop keeper till he was blue in the face there and the shop keeper threatening to call the police.... Gotta be careful and wary of the sellers....
Mongkok is more like Funan..... more proper, but still gotta make your own checks.
Good luck !
