Forties dinner buffet
The Los Angeles public library has a historical restaurant menu archive online, which will allow you to search restaurant menus for specific years.  It will give you an idea of what fashionable people were eating at that time.  The menu archive is a GREAT way to find ideas for period cuisine.  

EDIT: I have a second historical menu archive for you! Collectiblemeals hosts a collection of menus for famous meals, including many presidential dinners.

Add in some Moroccan fare and a splash of French haute cuisine, and you should be able to build a historical and delicious menu.
