Hello dude I'm kinda also ABC + Mainlander but I've been clubbing for the past few months. Tazmania Ballroom and Azure is pretty much drink and chill place, with some dancing with alot of non-locals. I would go Beijing (pretty much dancing) if you wanna meet locals as alot of Honkies go there.
If you want to head to Tazmania though you need a booking or try to head in before 8pm.
For a dude's night out I'd definately recommend FLY, they have Pressure Hour on the last Wednesday of every month. From 6:30pm onwards it's free beers for everyone til someone pees or leaves the venue. the last one lasted about 1 hour 42mins. and they have giant jenga
