That's gonna be a long list! Go here:
http://beermapping.com/maps/citymaps.php?m=portlandor and just start working your way through them. McMenamins are everywhere, each one has a lineup of solid beers and good food with some variation in the menu and seasonals. Raccoon Lodge is close and good. The Dublin Pub has like 100 taps, some fresher than others. Downtown, most places are in the Pearl district - Bridgeport, Rogue, Deschutes. Cross the river and Green Dragon, Roots, and Lucky Lab are all close together. FH Steinbarts is where you'll be getting your supplies and going for the Oregon Brew Crew meetings. God, I miss Portland!
