Hot spots in and around Redmond

I love my home office (and the fact that I can work from home), but I'm starting to lose it a little bit. Not enough to go into the office. But I'm starting to talk to the dog (more) and look forward to the sound of the postal delivery truck. Most of my collaboration at work happens virtually (my manager is in NC and my team is all over the US). I get plenty of human interaction during the day, just not face-to-face. And I'm totally fine outside of work (and we know we don't talk about that stuff here); just need a little change of venue for me and my tablet PC.

So for any local readers, what I am looking for: fun hot spots in and around Redmond where I can park it for an afternoon and work; preferably ones with some kind of caffeine delivery system. What do you know?
