I love checking out new breweries, brewpubs, distilleries, speakeasy-esque cocktails bars and the like that feature local spirits/beers. Where are the best in Austin?
Oh man, there are too many to list.
My all time personal favorite for craft beer would definitely be Flying Saucer Draught Emporium. You can't go wrong here!
If you are wanting to bar hop and want a less club vibe and a more "twenty somethings" vibe then I would choose Rainey Street over 6th Street. (Though, 6th is fun if your looking to get weird).
Mentioned in this answer:
Jester King Brewery is a great spot in Austin! It's a little out of the city but worth it. The pizza is so good too.
