Domy has an awesome art installation that depicts Jack The Ripper's final murder scene. Pretty graphic (i.e. don't take your kids there).
This book outlet is perfect for zine-geeks and artsy people alike. There are unique trinkets and awesome design posters. If you're visiting Austin and want to take back souvenirs, consider Domy.
Awesome Kid Robot selection.
This is the most interesting bookstore in Austin.
