Subway Watermelon Cucumber Agua Fresca

Subway Watermelon Cucumber Agua Fresca is a thing I found when walking into an Anaheim Subway. The watermelon is lost in this drink but the cucumber is definitely there to tell you to think this crap is good for you. For all I know it should be brimming with nutrients. 

I wouldn't say this is a good idea, but if you drink less of this than soda then good deal.
