Cortilla, if you happen to night-stop in the St Just area then I recommend The Star - good accommodation, excellent breakfast. You'll need to book though. The weekend we styaed there it was in the Telegraph as one of the UK's top ten unspoiled pubs (or something like that!). You'll need to dine elsewhere though, they don't do evening meals - pub across the "square" was good.
We walked the coastal pathway from St Just to Lands End, advice - don't do it pi$$ed!
And yes, I'll third the Blue Anchor at Helston!
