Sha Tsui and Pacific Place both have branches. Best market for first timers - kind of touristy now. I think the night markets are better, but we did find a good silk dress here for my wife after comparing against the big Chinese department stores for quality and price. Take the 6 or 6A bus from exchange square in Central. Best fruit and vegetable market adjacent to the Jade Market and Jardine's in Causeway bay.
First half is fruits and veggies.
Second half is dry goods. Li Yuen Street East for non-designer handbag, Li Yuen Street West for Satin coats and vests. Restored colonial market building was as bad as Central Market. Many unique shops. Very aromatic food market with fresh meat, etc.
