How many courses are there in a typical French sit down meal?
Not sure about courses but I would often sit down to dinner in France about 8:00pm (this is the typical dinner hour over there) and I would still be at the table eating after midnight. The whole secret is to pace yourself, never eat too much too quickly. Make sure you know exactly what is coming. It is rather embarrassing to be full before even the main plate arrives, which I would do at the beginning. Eat very slowly and chew every bite, there will be tons of food and you will have more than enough time to eat it all. French food is amongst the best in the world and you will enjoy it. Have fun!
