Why is everyone saying Hong Kong. I live here and I still like to pop down to Bangkok to get the real good stuff. Go back!!!
Lots of culture, friendly people, cheap as chips and they have:

This is the mother of all markets. Best time to go is our winter as it is not as hot and less rainy. But I'm sure you know this. Hong Kong is okay and Bangkok rocks. I only wish we had an office there but my choice is Singapore or Hong Kong if I want to be in Asia. No space in Jakarta and our China JV partner went bust on us
I also like Bali but the shopping isn't as good or as organised although you can get great batik art at reasonable prices. Not as easy to get around as Bangkok or Hong Kong though.
