On a route through French Brittany we went to this restaurant. The waiter speaks Spanish and in any case they do their best to serve you. They have a menu with salad, cookies, dessert and coffee or tea, and most importantly for celiacs, a gluten-free option!!! Very good price and quality.
Located in the center of Dinan a stone's throw from the clock tower, it offers quality crepes and they are also gluten-free (the savory ones). Fast and helpful service.
