I'm a big fan of patronizing the local small shops rather than the chains. Unfortunately this place is about 25 mins from my house by foot, so not always the most convenient. I normally grab a cup if I'm at the organic grocer or Ed's ice cream right on the same block.
The people are really friendly here, and they serve organic free-trade coffee for the same price as a cup of coffee else where. If I lived closer I'd definitely be a daily regular. They also have baked goods which look absolutely scrumptious but I haven't tried it yet.
