Zoka

There are two in the Seattle area. One off Greenlake, the other around the University District. I've only been to the Greenlake one, and I love it. Their Chai (either spicy and sweet) is amazing, their coffee is great and their food (savory or sweet) is fabulous. It's always a bit crowded and hard to get a place to sit, but when you do sit down it's worth the wait. The seats are comfy and the atmosphere is so inviting that you feel comfortable sitting by yourself or sitting around one of their many, rather large, tables in one of their, also large, chairs. Baristas are friendly and eager to please.

I recently tried their "comfy latte", which is heaven in a mug.
