Mosaic Coffee House, a new pay-as-you-will coffee house in the Wallingford neighborhood of Seattle. Intended to promote healthy community, this service of the Seattle First Church of the Nazarene features coffee, music, and a separate room for children. 60% of the tips 10% of all proceeds go to charity, with a different charity each month. [They no longer collect tips. Thanks Tim in the comments.]
They're on 44th and 2nd, with the entrance on 44th.
Hey, it was mentioned that 60% of the tips that mosaic gets go to charity... they've switched it up... they now don't take any tips, and 10% of all that they receive in go to a charity which rotates each month.
