There's a local chocolatier here in the Seattle area that makes a real nice dark chocolate sauce. Fran's Chocolates.

Now, with respect to ice cream, the only place to go in the Seattle area is Theno's Dairy in Redmond, WA. http://www.thenosdairy.com/

I highly recommend it to anyone here who's either visiting the Seattle area or who lives in the area. Well worth the drive from Seattle, or even from Everett, maybe even from Tacoma.
