One of the more easily obtained brands of coconut water available in the UK uses the slogan "like sticking a straw in a fresh coconut". Well, they're lying, and now I know because what you get at Joez is a green coconut with the top lopped off before your eyes. If you want, they will transfer the contents, including the meat, into a cup.
And wow, it's one of the most amazing things I've ever drunk. Wish I could get green coconuts back home!
Cons: Hard to find, Not in Edinburgh!
