They have really good Thai food. IIRC, we went to Phuket near the Space Needle, Thai House, and Phnom Penh Noodle House, and they were all very good. I watched football at a place called Sport on the south side of the Needle... they have some good microbrews. There's also the 5 Point Cafe just south of the Needle... they have a 6am happy hour. If Flopnuts shows up, he'll tell you to go to Dick's.
EMP and the Science Center are cool. We hiked up a mountain in Olympic National Park and I learned just how much my cardio sucks.
I was wandering around one day and someone asked me if I needed a place to smoke crack, so it's a very tourist friendly town when it comes to finding things you wouldn't necessarily find on Google maps.
