Rather pleased they showed the Eglise du Brou in Bourg, opposite a great all-you-can-eat restaurant where we filled up on our Strasbourg-Perpignan diagonale in 2012. We'd had the same togs on for the last 400k so they put us at a wee side table out on the pavement.
Worth the visit, that place was. It's called l'Authentique. It might have changed since, but still...
