The mother of all street fairs in Portland is the Last Thursday of the month during the summer on Alberta Street. Actually I think the street fair extends into the spring and fall, but I was there yesterday (July 29th, 2011), and it was awesome. There are street performers on every block, artists and artisans, musicians, food carts and of course all of the restaurants are open and many have sidewalk service.
They block off Alberta from about 20th to 30th streets, and the show begins at about 6pm. It starts softly and quietly, but as the afternoon progresses the noise level increases and so do the crowds. My personal favorite is the marching band with the performers on stilts.
