My absolute favourite is Japanese book store Kinikuniya.Books expect to spend at least 2 hour in there. The cafe serve amazing chocolate cake to recover for your book-a-thon browse.
The coolest library award goes to Customs house library
Looks like a cool club fancy sofas flock wall paper and the glass floor housing a tiny model of the city.
When you have finished reading the newspapers of the world you can pop up stairs for a cocktail
at Cafe Sydney
