I've been in Austin not quite 3 years. Prior to moving here I lived in Philadelphia, Tucson, and a few other places. Found some great coffee spots in those places.
Austin - over on 5th and San Marcos is a nice place -
Progress Coffee.
I also like
Genuine Joe on Anderson.
Neither of these places has ever been really crowded when I've gone, they serve a nice cup of coffee, nice food items and pretty good ambience.
