There are many places in Hong Kong that know how to party. For me the big thing is finding a place that rocks that isn't too far away. What good is a great party if you need to travel stupid distances.
Up on the North side of Hong Kong I'd like to think the North District Social Club knows how to party. They have a Facebook group (click here), a YouTube Channel (here) as well as a group here on Hong Kong Stuff (here). The events are frequent, if you live more around the Northern New Territories you'll be pleased to see a few events per month.
