Cafe Ladro is one of the few organic coffee places I've found in the city. I used to frequent the downtown location because it was just a couple blocks from my office. Today I hit the one on Capitol Hill. There are both consistently good.
The coffee at Ladro is good. The baristas are funky and friendly. The pastries are good (downtown they have a carrot cake cupcake that is fantastic).
Wi-fi is not free, but the nice folks at the store today offered to give me the credentials to bypass the payment (I declined). I suspect this is SOP.
