Green Tea Coca Cola?!?!

I went to Mitsuwa (awesome japanese grocery store in Edgewater) yesterday to grab some lunch in their food court and I scanned the beverage isle to find something to quench my thirst and I saw the weirdest thing.  Green Tea Coca Cola....

I wasn't brave enough to get it because when I imagined the flavor combination in my mouth, it didn't seem so tasty.  Has anyone tried this?  I might have to go back and get it because I'm just way to curious.  Who knows I might be pleasantly surprised.  It's a pretty advertisement though!
