I actually stayed at that Chifley for work trip a month or two ago, completely unaware that there was a micro there. Imagine my delight upon rocking-up and seeing the sign pointing to the micro-brewery and bar downstairs! The sad thing was that I had already made dinner plans, so there was only time for a quick reconnoitre and one beer. Probably could have been two beers, but the one I had was some kind of high alc % lager from memory, maybe a doppelbock? - and I had to drive. They definitely have a proper, shiny brewhouse in there, maybe around 5 or 6 hecto? It was squeezed into a glass box near where you enter the bar from the lifts. Didn't see where the fermenters were, I think there was some more stuff outside in the 'smoke garden'. The bar is down a floor from the Chifley foyer, or you can access it from outside but the outside access is not immediately obvious. Can't remember a lot about the beers on offer, I think they only had one or two in their line-up at that stage, but some other beers of interest on tap or in the fridge. Would certainly be worth swinging off the highway for a look if you were going past anyway, although prices may reflect the fact that it is associated with a large hotel chain.
