Hope you come to visit me at Espresso Vivace in the Cascade area of Downtown. Let me know when you're gonna be in town and I will let you know when I am working!
Espresso Vivace is a must if you want to see commitment to cafe espresso to an obsessive level. I would also recommend Stumptown; they have a new place in Seattle, though they are originally a Portland-based company. Go to Victrola for sure. They have the best capps I had in Seattle. If you want a busy, college-y feel go to Zoka. They have a great setup.
