Lindsay,
Yeah, I was gonna suggest Omnivore.
Are you just looking for independant cookbook stores? What about general bookstores which have exceptional cookbook collections?
Anyway, your second could be "Powell's For Home and Garden" in Portland, which is their branch bookstore which is only cookbooks and gardening books:

http://www.cookbookjj.com/Don't know anything on the East Coast, sorry. Oh, wait! I don't, but Kris does. Kitchen Arts and Letters in NYC:
http://www.kitchenartsandletters.com/You totally owe me a free cookbook now. Or at least a pamphlet.
