If you find yourself in Arles and you’re looking for lunch, I’d gladly recommend Cuisine de comptoir. If you get into town via the train and do the common sites in town (the Roman arena, theater and the van Gogh sites), it’s at the far end of your walking itinerary. We had a classic Provençal lunch of tartines and a half carafe of rose. You should do the same if you find yourself there. We’ve gone tartine crazy since we’ve been back.
