It seems like everywhere you look in the neighborhood now there's a new cafe/coffee shop. But that's cool with me as long as they're offering good service and tasty treats/coffee.
The latest is Bittersweet, in former home of Location-Location-Location (which has moved to S. Portland by Pequena in a very cute space), offers simple decor close to the park (this is key when walking home with the dog, right around the time you realize you need a coffee, badly). They also sell pastries from Balthazar. I've only stopped in once (the day I left for Poland), but damn, the berry scone I had was great. I also saw Keri Russell walk past me on the street that day, as an aside. A friend tells me the iced Americano is THE best coffee in the 'hood right now.
Per the Village Voice, they also offer some interesting ice cream flavors as well...
