If you are in Pioneer Square go to Diva Espresso just off the lobby of the Smith Tower: Super friendly staff and quiet place.
Did you ever go to the Bauhaus Books and Coffee? It was at the corner of Melrose Avenue and East Pine Street, close to Melrose Market. The building is being remodeled now so they closed the place down and I miss it.
However, they reopened no more than one block away from the former place. They still have the bookcases filled with old books and what I particularly like is that it is now oriented south and really sunny in the morning. They also have a nice deck on the second floor.
On a sunny early spring morning, I had a very tasty Cappuccino to start my day and decided where I would head.
