I got Dublin Dr Pepper at Pita Pit yesterday mostly because of this post. (I also just wanted caffeine.) It was good, but since I switched to Coke Zero permanently, the real sugar tasted too sweet. I've gotten used to the aspartame aftertaste, I guess. And Diet Dr Pepper remains the first good-tasting diet soda and my go-to in restaurants that haven't fallen in love with Coke Zero as I have.
