I first heard of the flavor of soda "Green River" watching an episode of Diners, Drive-ins and Dives. Host Guy Fieri was at the Southside Soda Shop and Diner in Goshen, Indiana. One of the proprietors of the joint made Guy a Green River ice cream soda (made the old fashioned way--hand made with syrup and carbonated water from the fountain.) I never once thought I'd actually run into the actual soda, Green River, after seeing that on Triple D, but here we are; thanks to the newly opened up, Fresh Market in Horsham, PA.
As for taste, harkening back to Triple D, Guy, for some reason tried the syrup straight. He described it as "a liquid Life Saver." Well, the soda itself does bear some resemblance to a green lolipop, but thankfully not quite as sweet. It does use natural lime oils for flavoring. Seems they got the balance of citric acid right as well, as the taste is not too harsh either. All in all, my experiences with lime sodas aren't too wide (ranging from pretty good to crappy), but so far, I would have to say this is the best I've had of them.
Sweetened With: "High Fructose Corn Syrup"
Verdict: Worth trying at least once
