Well I am French, and totally blown away by this post existing at all, as well as the replies, what a waste of time. Firstly French food is amongst the worlds most finest. Secondly, France isn’t the 3rd world, the majority of fuel stations offer salads and sandwiches at a modest prices. We even have Coca Cola, and energy drinks

. You make it sound like you are taking your Cali to the Falklands. Don’t worry, you will eat very well, gain several pounds, and relish your expedition. Now if you wrote here about French drivers and driving, I’d understand, but food, no lol.
Enjoy your trip
