I'm around this part of the UW campus all the time, so I stop here maybe once or twice a week. The coffee is consistent and quite good - their roasts come from a local co-op called Just Coffee. I can't speak for the sandwiches/lunch menu because I've never dined here, but I do like the pastries - the usual coffee house suspects like muffins, scones, cookies. Some of the varieties are atypical - blackberry scones, ginger-pear muffins, and the like.
My favorite part: the exterior wall is usually pulled back on a nice day, making everything open-air. A nice place to sit in the morning to do some reading or people watch.
