To answer the question in the title of this post, I must be honest. The food we have been served in France has been incredibly delicious.
The owner and chef of Sous L'Olivier where we are staying has cooked and served us fantastic food and introduced us to new flavors and new methods of cooking. He has also taught us about the "digestif", a wonderful small glass of liquour that you sip at the end of the meal.
At home I am able to say no to dessert or leave food on my plate when I am full. The only will power I seem to have in France is the will not to lick my plate because the food is so delicious.
All I can say is what my daughter taught me to say, "yolo", you only live once.
