I am neither a bride nor a groom, I was in fact the photographer for a wedding at this gorgeous location this summer (July). As far as locations go, this is one of the nicer affordable ones I've seen. It's quiet and rustic, with a beautiful lawn for the ceremony and reception, while not being too far from a urban hub (Issaquah and Bellevue). The whole property was well tended and kept and looked stunning, clean, and green. As a photographer, it was a pleasure to shoot at this location, making it much easier to get the photos the bride and groom wanted.

Some sample pictures from a ceremony on-site can be found here:

I worked with Kathy from King County Parks and she was so helpful. You can do so much with the space if you have a little creative flare. Would recommend this venue to any bride that wants a nice outdoor wedding!
