Favorite foodie day trips/tours near Seattle?
Depending on how far you want to go, there are lots of wine tasting opportunities. Most convenient is Woodinville, in the 'burbs only maybe 30 minutes from downtown, with lots of wineries and upscale places to eat. If you want to stretch your trip, the Yakima Valley wine country starts with Yakima (2 hrs over the pass, a nice drive) and stretches to Prosser (maybe 3 hours) -- the wine generally improves as you head east, and there are tons of great taco stands all over the area.
Depending on the season, of course. :)
Taylor Shellfish can be fun. Should call ahead to see what's in season. Mike Rowe featured them on "Dirty Jobs" once, too.
Haven't been to these places, but they sound nice: Bow and Edison
Have a delicious day trip to the agricultural communities of Bow and Edison
There's Tillicum Village, of course...
