Can't say enough great things about La Finca! Great tasting coffee, sunny spaces to work or chat with friends and a decent but small menu if you wander in and are feeling munchy. The back deck is a bit small, so get there early if you want to claim a spot. The little work/meeting rooms are also hot spots - but totally worth the time to get one to hang out on.
Only issue perhaps is the price of coffee. Not cheap! If you are a princess about your coffee though (looking at you, Aussies!), you will probably really like the beans they use and they way they draw a proper cappuccino.
