Just been there for lunch with my wife. We hadn't reserved and it was pretty full but they found us a table. Menu du jour was quiche, steak and chips, apple tart and was delicious for €15, even including a small carafe of wine. My wife had warm goats cheese salad and she said it was great too.
We were clearly tourists and this is not a touristy place, but we were made very welcome as we tried our best to speak French. The next table was a multi-generation french family celebration who all seemed to be enjoying their Menu Terroir. The bill was very reasonable and I would go back in a heartbeat.
