Depends on what you're looking for, and what part of town you're in.
If you're downtown, the above recs are great. Might also check out Upright for farmhouse styles; Base camp for lagers, Commons for Belgians.
Taprooms close-in: Apex, Bailey's
In Southeast check out Gigantic, or Hopworks
In Northeast Laurelwood is good
In Southwest try Sasquatch
In North try Amnesia or Hopworks (Sareveza or Bridgetown are good beer bars here)
In St Johns try Occidental for German styles
In Hillsboro try Vertigo
There's tons more but these are what I'd hit with limited time.
Enjoy!
