A very popular and common dish served all over the place is Moules Marinieres. This is the shellfish mussels, cooked in white wine, or sometimes cider, with onions, garlic, cream and a variety of herbs such as parsley, thyme and bay leaves.

Yes you have to get in and take the mussels out of their shells, but it's very easy, you can use your fingers, a fork, another mussel shell, or just bite it out even.
Moules et Frites or Moules Frites can be found on menus all over France. It's moules marinieres served with chips, or french fries, depending on what you call them.
