Ok, I'll give it a shot.
Spend part of the day on the waterfront -

then go here and check this out -

and while there, have lunch here (the chowder is good, and a friend of mine created some of the dishes on their menu) -

You can also have a nice sushi here -

For nightlife, I like the Fremont area (because I live right up the street) -

If you want to see a show, grab a copy of The Stranger and take your pick.

Have a good time in Seattle!
