I had this as a caffeine boost 2 days ago:
Brand: Johnnie Ryan Diet Soda.
Origin: Niagara Falls, NY.
Purchase Place: "Minnesota's Largest Candy Store," Jordan, MN.
Review: This tasted like a good cola. I was thinking it was pretty decent with a rich, almost berry flavor, and that it was alright. Then I remembered it was diet, and was quite impressed. There's a lot of flavor here for a DIET soda.
Score: 7 out of 10.
