Go for a different kind of coffee
Check out Slate Coffee, a small and naturally lit cafe just up the hill from Ballard's main drag. They serve deconstructed lattes in the kind of glass you might not be used to drinking coffee out of, but that should totally impress your date.
Rally with the girls
Watch the Rat City Roller Girls get down and dirty over roller derby at the Shoreline. Practically a Seattle right of passage, this sport can be a little hard to accurately explain, so we recommend just going and watching tattooed women and other badasses throw themselves into each other until you get it.
