I don't know why they don't just call it by it's real name:The nectar of the gods.
Not sure where you are but I see the Chicken Express fast food places around Dallas/Ft. Worth have Dublin Dr. Pepper in their drink dispensers..
My friend in Ft.Worth is a little put off by Chicken Express's sign with a dead chicken on it.
Chicken Express is the best fast food chicken place. I really like their stuff and #2 son is addicted to their gravy. We are good friends with a guy who now is very wealthy from running several franchises. He and his wife and kids were living in a double wide and working ungodly hours running their first store. Great guy!
