Dick's Drive-in is one of the most famous eateries in Seattle. If you ever come here, GO THERE. They have probably less than 20 items on the menu, but what they do have is great. Get a bacon cheeseburger, they're the best (mind you, this is coming from a vegetarian).
My cousin Zak had a plain cheeseburger and a chocolate ice cream. So i took a picture of it. Nothing too amazing. :)
