Heading to Dover , come off at the A2 at end of M2 towards Dover first lay by after checkpoint. Walk through hole in edge to snack bar (eat in or take away).
Not sure about opening times.
Food is very good value for money and it is spotless. (it is worth paying the 50p or so more than the ferries as the food is all fresh and edible).
I came past there one dark night & saw a new car parked neatly upside down,on its roof. Phoned the police on the mobile. Never knew what happened…?
