Great coffee, decent food, free wi-fi with plenty of seating on two floors in an eclectic and unique setting just off the Capitol square. Very "Madison" (that's a good thing for you unfamiliar with Madtown).
The upstairs balcony seating is the best, especially if you can score a table by the windows overlooking the streets below. Nice people watching spot.
Oh, and they also serve and sell wine (by the glass or get a bottle to go). Makes knocking out that last work email of the day a little more challenging then usual at times...
