Visitors to the double-decker bus, which is disguised as a giant cucumber, will be offered a selection of Hendrick’s cocktails as they tour London.
The bus, named "Hendrick’s extraordinary roving bus for exceptionally refined travel" (or H.E.R.B.E.R.T for short), is designed to offer Londoners an alternative option to the sticky summer commute.
Sam Bovill, Hendrick’s brand manager, said: "The campaign is aimed at bringing moments of delight and peculiar humour to the otherwise everyday, mundane task of commuting."
The campaign is accompanied by a social media drive via Hendrick’s Facebook and Twitter accounts, with passengers encouraged to share their commuting conundrums using #HendricksMinistry.
The bus will run between 21-29 July (excluding 25 July), from 4pm-9pm.
