Had this in a mexican restaurant recently, basically desperadoes but without the price tag. http://www.globalbrands.co.uk/amigos/default.asp
Quite hard to find online, but im getting the shop i mentioned above to look into ordering it for me.
Cool Desperados are just stunning, i can't say anymore than that
I go to Macro's and buy a crate for like 19 quid for 25 bottles
