The franchise will be operated by Marche, known in Slovenia for its highway rest-stop restaurants, or its owner, the French travel and hospitality group Lagardère Travel Retail.
The new Burger King outlet will open at the Lom 2 rest area on the coastal highway to Koper, alongside an existing Marche restaurant.
The opening is scheduled for the second half of December, with a design similar to Burger King locations in neighbouring Croatia.
In Croatia, Burger King operates under Marche at the Draganić South rest stop and in Zagreb’s Arena Centre.
