Austin Beers

Heading down to Austin next week for a bachelor party and was wondering what are some beers I should be looking for. I've never been to Texas so this would include any Texas beers that aren't widely distributed I guess. I don't think we'll be hitting up any breweries unless there are some in the main part of the city but I'm sure we'll seek out some good beer bars. I'm not necessarily looking for rare beers but more beers that a place with a decent selection might have.

Thanks!
