The enlarged Central Terminal lounge has showers, a proper hot-food offering and a full bar, with more substance than most shared-use lounges at SEA.
It remains a major crowd magnet. Recent traveler reports describe regular waits of 30 minutes or more, so join the list early and do not rely on getting in shortly before boarding.
