Don't know. According to Andy, yes.
Ummm... I've been to a couple hens nights now, and I know they'd be vastly different, but one place that always stands out is zenbar. Go there to start, have a feed, and they have decently priced drinks too. http://www.zenbar.com.au/
Chill on Queen is a personal fave of mine, simply because they have SO MUCH VODKA!!! http://www.chillonqueen.com/
Other than that, any pub is good to run amok in
