It would help to know where you are going to be, but here are a few ideas:
Seattle Fine Dining:
-Canlis (prob. #1 fine dining in Seattle)
-Pallisades (on the water in Magnolia)
-The Six-Seven at the Edgewater Hotel (Seattle Waterfront)
Nice Restaurants:
-Ray's Boathouse (on the water in Ballard, large patio w/ good views). Love Ray's for Happy Hour...
-Daniel's Broiler (go to the one in Leschi for views across lake Washington toward the Cascades). The Leschi Market across the street had some good deli items.
-Sky City at the Space Needle. I wouldn't call it the most amazing food, but the view................
-Etta's (near Pike Place Market). Owned by the same guy (Tom Douglas) who runs Dahlia (mentioned earlier) and Lola - all good choices...
-Il Bistro (Pike Place Market) Best Italian I've had.
-The Icon Grill (Downtown) American comfort food like you've never had it...
-Bastille (Ballard) Excellent food. Large patio for a nice day. I go here with my girlfriend a lot.
Local Flavor:
-King's Hardwear (Ballard). Frequented by the guys in Soundgarden.
-Circa (West Seattle). If you will be near Alki, make the trip into West Seattle to Circa. Unassuming place with AMAZING food!
-Red Mill...gawd, I'm getting hungry...
-North Lake Tavern (Lake Union, near UW) Good pizza.
There are also lots of farmer's markets with fresh food made with ingredients from the Northwest.
