Gorgeous location and good use of local produce.
This is definitely one that I will come back to.
I hope you give it a try too

They do both meals and accommodation

This is one of those 'location' places that's worth visiting.
Go there for the surrounds and the picturesque views.
Food is on offer, so get a tasting platter if you're interested and they do have a good range of wines to match.
But I reiterate, it's more the views that will be of interest. If you want someone to know the beauty of Willunga, they can stay in the accommodation they have here on offer also.
