For a coeliac abroad, whose French is limited, this is a good choice when in Menton. They do a range of buckwheat galette dishes. Just ask for the sweet crepes to be buckwheat, check other ingredients and you’re good! Very tasty. Once I mentioned I needed gluten free the owner was right onto it. The waiter was less knowledgeable however. Overall we’ve found it difficult in France to find ‘gluten free’
