Cool things to do in Seattle?

I’m going for work and will only have a few hours of free time. My hotel is downtown. I think I’ll be close to the space needle and some market people keep mentioning. I’ve never been there. I’ll probably have a few free hours during the day, so daytime, brief activities are best. I also love food so any good food recommendations in or near downtown also appreciated! I’m sad it will be so brief!
