Place to stop between Honiton and Exeter

[Harleyboy]

Hi,
I could some expert help please? I am involved in a corporate event taking 12 cars down to Devon. We're looking for a place to have everyone stop for lunch that doesn't stray far from the A303.

Can anyone suggest a (non dogging) picnic area type place where we can either buy speedy snacks or enjoy a pack lunch?

We're on a time deadline so don't have time to go elsewhere.

Thanks a lot!!

Thanks chaps, the diner looks a good option!
