I had first seen this type of Cola Vending at Firehouse Sub (link at bottom of post) except this one is black instead of red. This was at the Southgate Plaza Burger King off of Pettit near the Lafayette intersection in Fort Wayne, but I am sure they are popping up elsewhere as well.
It offers several different types of Coke, Diet Coke, Caffeine Free Coke/Diet Coke, Dasani waters and other Coke Products with different flavors added such as Lemon, Lime, Vanilla, Cherry, Orange and Raspberry to the base of many beverages.
Having a Diet Cherry Vanilla Coke out of it was sort of like the old-time soda fountains of yesteryear but with the machine doing the mixing instead of person. I also enjoyed the Raspberry flavored Diet Coke as well.
Marv said he saw a segment on television just the day before where there is a computer in the machines that sends information on what is selected at each machine at the end of the night for stocking and sales purposes.
