The Whiteaker or "the Whit" as the hipsters like to call it, is the cool kid / industrial district by the train tracks. It used to be a working class/industrial district, but more recently has been a center for artists and activists. In the last couple of years the number of restaurants and breweries has been rapidly growing. The neighborhood is host to number of seasonal events, including the Whiteaker Block Party which happens during August.
There are a few articles about the neighborhood, its history, and gentrification here.
