So alright, this isn't your conventional mary. But cocktail wizard Tony Conigliaro's Prairie Oyster is a twist on the classic with all the flavour of the original but none of the looks. It looks even better, in fact; a deconstructed version served in an oyster-shaped vessel. Its spherical yolk is filled with clarified tomato juice bobbing in a sea of horseradish vodka and the drink’s usual accoutrements. Knock it back in one gulp and order up a round for your pals.
