If he is an artist I would check out western ave studios. It's a community art building and they have an art show event this weekend, plus there are a lot of artists in there so just walking the gallery is a ton of fun. Navigation Brewery is also there so if you like beer they have some good stuff!

As for food if you have room after Olympia I am a huge fan of 1981 Ramen Bar and Tasty Dumpling, they both have really good food.
