We had dinner on the terrace, service was slow and not friendly, food was ok and overpriced, will not go back.

Stayed en route to Switzerland and on the return journey. Both times we had a superior room to give us space for our travel cot and the room was perfectly nice. The hotel is a bit strange in that the reception desk person seems to do everything - check-in, bar, waitress.... so there can be a bit of a wait. And don't expect a smile.
The restaurant is rated highly in the Logis de France guide. We ate there both times, - first time (a Friday) we all had the set menus and the food was good. The second time (a Saturday) only one set menu applied so we chose from the a la carte. What a huge disappointment after our first experience. Partner and I had quiche a la fromage blanc. The puff pastry was soggy and the middle was super-heated, classic signs of being microwaved. My partners main course of salmon was so tiny that we debated asking the waitress where the rest of it was! Conversely my mother had a dish that consisted of a massive pile of choucroute and about half a pig.Not exactly exciting cuisine.
As for breakfast, 15 Euros will get you coffee out of a machine, some bread, hard croissants, jam and a few options of cheese and ham. It's really not worth it and I've had far better breakfasts in France for less. If you have to stay here, then there's a boulangerie down the road that does petit dejeuner for Euro 1.50 (coffee and a massive pastry)
