Coca-Cola will announce Friday the newest customer for its Freestyle fountain machines. The Atlanta-based beverage giant has struck a deal with the Five Guys burger and frieds chain to put the machine in all its company-owned locations. Five Guys has been testing Freestyle machines in the Atlanta market since 2010 and expanded testing in multiple markets in 2011. The touch-screen Freestyle machines allow users to mix more than 100 different flavors of Coke-owned and distributed brands together from one source.
