A BK down the street from me that was closed for a long time and remodeled reopened with a Freestyle, at least according to the freestyle locator website. Haven't been in there myself to confirm.
The Coca-Cola company posted this today:
Top ten exclusive Freestyle drinks
1. Barq's Vanilla
2. Coke Cherry Vanilla
3. Minute Maid Strawberry Lemonade
4. Sprite with Strawberry
5. Coke with Lime
6. Sprite with Peach
7. Hi-C Strawberry
8. Minute Maid Raspberry Lemonade
9. Sprite with Cherry
10. Coke with Raspberry
Looks like Sprite people are the most experimental. Maybe Coke should do some brand extensions.
A couple of the Burger Kings here have them now. Although they completely re-did one close to me and did not install a freestyle machine.
