Schweppes is hosting a miniature bar inside a hackney carriage to serve gin and tonics.
Customers will be picked up by a private driver on 13 December and have their drinks served by a mixologist.
The black cab’s interior has been decorated to resemble a "luxurious Christmas bar" with timber flooring, leather seating, garlands and fairy lights.
Guests will have the choice of two drinks during the journey: a Sleigh Ride, made with Edinburgh Christmas gin, ginger ale and tonic water, or a Santa’s Helper, which will have Ceder's non-alcoholic gin mixed with tonic water.
The rider will be able to submit pick-up and drop-off details for the complimentary zone 1 journey.
Sketch Events is working alongside 3 Monkeys Zeno to deliver the project.
