goodies stores in SF, DC and SLC
 

Hello everybody
I will have some time in the US.
Actually in Salt Lake City first, then San Francisco and then Washington DC. Tourists trip :)
And maybe some shopping too :)
I'm looking for address for japanese goodies stores and us comics goodies stores...
You know, some store where you can find not necessary DVDs but keychain, bookmark, figures, posters, postcards, books, games too.
Anything related to Star Wars, XFiles, DC Comics series and/or Marvel Series, Burton's Nightmare before Xmas, etc...

Thank you
