Airship is a local Coffee shop that has connections all around the world. They roast a lot in-house and for most of the other shops in the area. They offer all sorts of coffee training classes too. It's a fairly small, cozy place with quite a large production in back. This is the kind of place that's fairly busy, but not so busy that you can't have conversation with the baristas. If you want to drink and learn about coffee you found the place. They have a variety of blends that'll hit everyone's sweet spot. It's on 5th Street just before you get to J Street, so that puts it just a few blocks from the Square. Give it a shot!
