Pearl District for minimalists – A passion for sustainable style. Most everybody has their own shopping circuit in the Pearl District, one of Portland’s most-vibrant arts districts. Bounded by the Willamette River on the north, N.W. Burnside on the south, N.W. Broadway on the east and I-405 on the west, the live-work-play neighborhood covers more than a mile, so it’s easy to not stray from what you know. To get beyond our usual haunts, we turned the minimalist in us loose in search of all things clean-lined.
