By what we believe is our generous estimate, the world’s most expensive organic martini costs somewhere in the neighborhood of $23.76 (note: We’re writers and not mathematicians; these calculations took the better part of an afternoon) to make. The markup is about $641 what do you tip on that? Our advice? Skip the publicity ploy and ask owner-mixologist Deborah Gavito to share her under-the-counter stash of nacho- and bruschetta-infused vodkas. Those, we can vouch, are worth every penny.
