Thanks so much for everyone's help with venue suggestions/question suggestions, etc. We went to the potential venues yesterday (including 2 additional options as well), and absolutely fell in LOVE with Januik Winery. We were trying to figure out logistics of getting people to Seattle to go bar'ing for an afterparty, and realized that with it being in Woodinville (and having OOT guests stay at Hotel Sierra in Redmond), we could actually host it at our house!
One of my favorite parts of Januik as well is that you can bring in your own beer/champagne. Nick brews great homebrew, so it will be a unique touch, as well as super affordable.
