I forgot to take a photo of this one as my wife and I grabbed it on a quick trip to Mankato recently, so here's a photo from the web:
Brand: Faygo Diet Root Beer.
Origin: Detroit, MI.
Purchase Place: Kwik Trip, Mankato, MN.
Review: This had a pretty sharp bite - it reminded me of Dad's Root Beer. It wasn't my favorite, and I didn't find it that great. My wife, however, liked it a bit. It was OK, but I don't know that I'll get it again.
Score: 4 out of 10.
