I was just in Arles last week and had a nice dinner at Loup Galoue (not sure of spelling) Escargot, Bull Tenderloin in red wine sauce it was a good meal with a great atmosphere. I think 3 courses was 28 euros, a bargain as far as I am concerned. There are only 28 seats so make a reservation. We walked in at 7:30 on a tuesday night and 15 minutes later the place was full. Try to drive to Uzes on the Weds or Saturday market day. In St. Siffret I had a great meal at L'Authentique.
