One of north Portland's strips of indie retailers, the liveliest section of North Mississippi Avenue stretches for several blocks and includes a mix of old storefronts and sleek new buildings that house cafés, collectives, shops, music venues, and an excellent food-cart pod, Mississippi Marketplace. Bioswale planter boxes, found-object fences, and café tables built from old doors are some of the innovations you'll see along this eclectic thoroughfare. At the southern end of the strip, stop by the ReBuilding Center, an outlet for recycled building supplies that has cob (clay-and-straw) trees and benches built into the facade. About a 10-minute walk east and running parallel to North Mississippi, the bike-friendly North Williams corridor is an even newer thoroughfare of almost entirely new, eco-friendly buildings rife with trendy restaurants, nightspots, and boutiques. Highlights here include Tasty n Sons, Lark Press letterpress printing studio and shop, Sol Pops handmade gourmet popsicles, and Hopworks BikeBar and eco brewpub. You could easily spend a few hours taking in both neighborhoods—North Williams has the better food scene, while North Mississippi is stronger on retail. To get here on MAX light rail, get off at the Albina/Mississippi station.
