Nantes is famous for its seafood, especially mussels and oysters. There are also excellent crepes and cider. I rank the tasting menu from Sources among my top 5 gastro experiences. The surrounding area is also interesting. On the salt flats of Guérande you can explore the old method of salt production. And in the picturesque town of Clisson, you’ll find a still-functioning 14th-century market.
