I've tried three times to follow instructions to post a review about Restaurant Le Saint Pierre but never got the email. I contacted TA to let them know and still heard nothing back.
Anyway, in case anyone's interested, I just spent a week in Arles and the best dining experience, though definitely not the most expensive, was Le Saint Pierre, right at the foot of the bridge that leads to the city center, on the Trinquetaille end (22 rue Jean Lebas). The owners, Christian and Helene, make it a point to chat with their customers (English/French/signing/good will). The food was the best I had in Arles.
We stayed at the Porte Camargue hotel, just a couple of blocks away, which was also lovely.
