We have used Fallot as our preferred mustard at home in California for years when available. The tour of the factory was very interesting and informative. You get to grind mustard seeds and make your own mustard. There is tasting of many kinds of mustard and a few pairings with food (not a meal, but good). The tour is in English and French. We reserved online easily. On arrival, it was not clear if we needed to get a paper ticket from the cashier (we did not). We had a little trouble finding it, thinking it would be a giant building extensively signed. We should have just looked for the mustard colored storefront and paid attention to the address! If you like mustard, this is the place for you.
