There are tons in Portland. Ken's, St. Honore, Pearl Bakery, Fleur de Lis, Baker & Spice, Blue Gardenia...the farmer's markets are a good way to check them out. There are several represented at both the Portland farmer's market on saturdays by PSU and the Hillsdale farmer's market on sundays. Two good resources for reviews are
www.portlandfoodanddrink.com and
www.extramsg.com . Extramsg has a whole photo album of bakeries and the farmer's markets as well as some really cool photos from the summer loaf festival last year. Portland Food and Drink is good for addresses, hours and website links when there is one for the bakery.
