The Seafood Fest in Ballard is worth checking out if you like your fish and crustaceans. Every vendor selling food must offer at least one dish that includes seafood. You'll find tandoori prawns, crab cakes, grilled salmon, etc. There are also plenty of non-food vendors hawking their wares. It's a good family affair, with entertainment, good food, and a chance to enjoy summer at it's best.
