Awesome coffee selection, great working environment. They offer a wide variety of beans, and will make a single pour-over of any bean they have. The barrista was very knowledgeable, and the bean he recommended for my taste preferences (the Costa Rican Noir) was exactly what I wanted. In fact, I came back for a second cup, it was that good. Reasonably priced (~$2.50 for a half-liter large coffee), with waffles and oatmeal in addition to the usual coffee-shop scones and muffins.
This was not the most absurdly gourmet coffee experience of my life, but the coffee was darn good, the chairs were comfy, the wifi was reliable (although there is a shortage of electrical outlets), and the service was excellent. I'll definitely come back next time I'm in Madison.
