About 30 minutes northeast of Seattle there is a city called Woodinville that has a ton of tasting rooms for Washington wineries.
For a fun Saturday, some friends and I rented a party bus and spent the day wine tasting! Sunny Saturday + friends + wine tasting = a good Saturday!
On Friday, we hit up a great restaurant I would recommend to anyone in the Seattle area - Westward. They have a fantastic outdoor seating area and the view is amazing. We were there for a quite a while and once the sun went down it got a little chilly, so they bring you out blankets!
