The July issue of Vanity Fair has an article about the halcyon days of the Paris Ritz and includes some stories about Hemingway. It's on their website at this link. I would like to read A Moveable Feast
EDIT: So I don't know why the link doesn't work properly but if you google "paris ritz vanity fair" it's the first article that comes up! You can also see the link under Recent Features below the error message. Be sure to check out the beautiful photos too.
