Aye, that's the best price for the AA I've come across. The standard is pretty consistent there and at the Regatta Hotel (they microbrew the AA and GA and were the only place in Brissie to get the Hop Thief on tap).
When I go out to other clubs around Bris that happen to serve the AA, that's where I notice the major differences in the brew. I'd say that has a lot to do with those places knowing very little about the drinks they serve.
