I stay in Hong Kong about half of the year. It's not my favorite city in Asia (the Chinese can be some rude fuckers) but there is some cool stuff. Mongkok night market is fun. If you want to get approached by a lot of Indian guys that say 'Hey Mr., want to buy a watch?' then check out touristy Tsim Tsa Tsui. The Big Buddha out on Lantau Island is a fun day trip...you can take the sky tram which will make it even better. Causeway Bay is great for eating/shopping. As mentioned before, most nightlife is centered around Lan Kwai Fong and Hollywood Road.
I will be back in HK for Chinese New Years next week, not sure I'll have much time with all the festivities but if you email me (
[email protected]) maybe we can meet up. Have fun and hope that helped!
Cheers,
