If you're ever in Fargo, N.D., on a Friday at 4 p.m., head to Sundog Interactive's Zen Café for catered food and drinks, and a few games. With participation in sports leagues and activities like Giving Tree of Hope, having a sense of community is second nature at this marketing and tech firm. (If you're cool enough you could join Code Freeze, the agency band known to rock out on the sixth-floor balcony.)
The open office looks and feels like a summer house. Brightly colored walls are lined with the work of local artists and pictures of staffers' family members. Four stocked refrigerators and a gas grill for cookouts make for a homey environment.
