For South Austin, don't go to South Austin Brewery they suck (beer and business practices). St Elmo is a must try at this point. Lazarus is killing it. I actually really enjoy Hi Sign, and you can't pass up Live Oak. Friends & Allies needs a little more time to hit their groove. It's been a while since I've been to H&G, but I've heard their tap selection has been pretty slim lately. Blue Owl is definitely worth a visit if you like sour/tart beer. 512 has that weird ticketing system now on Saturdays? You probably won't find much outside of their mainstays. I'm hit or miss on Zilker's beer, but they do have a cool taproom. PHP of course is a must try.
