It's it a boat wreckers yard?

No, it's a bar. Actually it looks better at high tide, but them I'd have been sploshing around in the sea to take the photo and in the dark, so not the best plan.

So try and imagine the waves gently washing around the feet of several stoned people sat on those stools, with surprised looks on their faces when they have suddenly released that the strange sensation around their ankles is really happening and actually the sea.
