Depending on what you like, this may be a good store for you:

I think that they have some of the best chocolates around. The availability in Portland has gone away, so I'm stuck ordering them when I'm in the mood. Fortunately, there is another local chocolatier with a good reputation (being the chocolatier to the Oscars is good, right) called Moonstruck that is spendy and acceptable.
