A Cosmopolitan is a yummy citrusy version of a martini.

Citron vodka, cranberry juice, Cointreau or Vodka, Triple Sec, cranberry juice and fresh lime served up in a martini shell.

And by all accounts, I'm SURE the PIP included some of these! As Punki said, life is too short and I wish now I had not let work get in the way of real life and joined the PIP as it sounds like an event never to be duplicated again!
