It's just about the only coffeehouse and wifi place in the suburb of Sun Prairie. I don't have kids but the space seems very kid friendly - there's even a kids' play area.
The service is friendly, there's usually sufficient AC outlets to plug in a laptop or other device. I've seen the place get very crowded from 8am to 9pm on weekdays, but the patrons thins out by the afternoon stretch.
I've also ordered their panini grilled sandwiches, they are nicely boxed "to go" if you ask them, with a side of greens.
