I came to use the Indie Coffee Passport. The service was absolutely lovely. Even though there was only one person ahead of me, the Barista asked if I wanted a glass of water while I waited. Strong coffee, but excellent. Espresso is served in adorable beakers.
It's somewhat hard to see if you're just walking by - you have to go into Willow Books. Not a lot of room (that I saw) to sit inside, but there's benches outside and there might be more space when the adjoined bookstore is open. You get a free coffee every 12.
