I love that "Seattle Premium outlet"... it's not even in Seattle!
You can see the original Nordstrom's store in Downtown Seattle across the street from where you catch the monorail to go to the Space Needle. You can also go to the original Starbucks which is located in Pike Place market. There is a very big Sephora downtown too (it's across the street from Nordie's).
Quirky stuff is really on Broadway which is on Capitol Hill. (It's a mini Portland if you've ever been there). There's plenty of reasonable (and delicious) food on Capitol Hill since there are a lot of students there.
I don't know what you're into, but if you like Native American stuff, there's also Tilikum Village (spelling?) which is nice to visit, especially if you can get the dinner show. I haven't been there in a long time so I don't know about prices.
If you like coffee, check out Victrola's, Caffe Ladro, Bauhaus, and there are so many more that I'd just have to run into them! There are some other good ones too, but I'm blanking.
