Made the close on 600 km to Roscof, so had to make a few stops on the motorway.
One of the best is Aire de Vendee. I got a triple chicken sandwich here (3 slice of ordinary bread), a bottle of Coca Cola and a dessert yoghurt (with spoon and serviette) for 5.90.
Bits and pieces of fruit, travel sweets, more coke, kept us going.
We didn't need much by the time we boarded the Pont Aven which was a pity as le Flora was open!
But we tried the self service. They had a range of hot dishes for around the 8 euro mark, also loads of salads, desserts, drinks etc.
Two Canneloni, two desserts, plus two small bottles (25 cl) of wine cost €27.65. The food was adequate (nothing special) but overall the value was decent.
