Wanchai is a must to shop too!
I believe most have already filled you with the places to go..
Basically, Hong Kong is a beautiful place!
I been there in May, just few mths ago and I so missss the place right now! The food is delicious.. the snacks will make u go "WOW" and the drinks..
I've been there a couple of times as my SO is hong konger.. he brings me to places where tour agency won't bring me! E.g. there's this street call 花園街 .. got alot of ladies fashion wear and its very cheap but no trying allowed as they do wholesale business ... it can cost like HKD40 for a very nice top which retails at least SGD20 in SG!! very good bargains there.! and since i am a mango lover, i always patronise the 許留山 there for mango desserts... and there's this old doutble storey 茶餐廳around the corner of 廟街 ( i think ) that sells very nice french toast and baked pork rice (炬豬排飯).. this cafe is so popular that Bryan wong and Xin Yue tuan went to visit them...
