Tretho Lounge

You walk onto Wharf Road and the water's right there—that's the St Ives experience Tretho gets exactly right. Inside, it's warm and unpretentious; the kind of place locals actually book for dates rather than just tourists passing through. The cocktails are genuinely well-made (not just sweet and forgettable), and the kitchen takes itself seriously without being fussy. It's pitched at that sweet spot where you can dress it up for something special but equally rock up in jeans after a walk round the harbour.
