I love Seattle, it has a special place in my heart (Mary and I were married there), and if it wasn't almost as cloudy as Louisville but with all the cloudy days put together in a months-long string, I could live there. We haven't been back for a while, though, so specific recommendations are iffy.
Some things don't change, though:
* Be sure to stroll around the Pike Place Market, and just wish Louisville could have something like that.
http://pikeplacemarket.org/* Bai Tong Thai may be the best Thai restaurant I've ever eaten in. It was founded by Thai Air people with the idea of serving Thai Air crews on layovers on Bangkok-Seattle flights. Bad news is that it's out near Sea-Tac. But you might be able to work out a lunch on your way in or out. Actually it would be worth the drive anyway.
