Seattle Brewery Recommendations?

Next week I am heading down to Seattle for work.  My boss and I are flying down with the first shipment of Wild Alaskan Salmon for a chef cook-off at the Sea-Tac airport.  If you want to know more or check out what I do for work, head over to our facebook page.
Ok, now for the real reason we're here... beer.  After I get done with work, I still have an afternoon, evening, and morning to spend in Seattle.  What breweries should I go to?
