There are some great places to get local food nearby.
The local community website has some links to local businesses including the Cuil Bay Kitchen Garden whose website is under construction at the moment
You can get amazing seafood fresh from huge tanks with lobsters and crabs and all sorts crawling about at the Loch Leven Seafood Cafe. They have a superb restaurant too.
And of course there is wild food growing around the place, look out for sea beet on the shore, chantarelles in the woods, and blaeberries on the hills
