The coffee goliath, which has rapidly been conquering Europe since it opened its first store on the continent in the alpine country 12 years ago, has joined forces with the country's national rail company SBB to open its first store on a train.
With the Starbucks name and distinctive green logo plastered across the outside of the two-story car, inside smiling baristas in green aprons offer up hazelnut macchiatos and skinny mochas in a setting reminiscent of the brand's static stores.
During the nine-month trial period, it will make two daily trips between Geneva and St Gallen in the northeast.
"We are going to be doing something for the very first time anywhere in the world, opening a store on a train," Kris Engskov, who heads the Starbucks in Europe, the Middle East and Africa, told reporters.
