There's a book that covers this nicely. It's written by a women that moved from Vancouver BC (although us Canadians hate to admit it, we eat like Americans) to France with her French husband. It covers the realm of French culture surrounding eating.

The most interesting part to me was the school lunches. It is frowned upon to send your kid to school with a lunch. Kids are expected to eat what is given to them, whatever the cafeteria staff decide to prepare.
