Wow, that's a small picture. That'll teach me to take my own. Anyways, I'd never tried this flavour of Coke before. I've had lemon Coke, I've had lime Coke, but not "Citrus Zest" Coke, which I suppose is some amalgamation of lemon, lime and the other citrus fruits.
The flavour is actually quite bold, and very nice. It covers up that "diet" flavour quite well, and it just felt like I was drinking a more interesting lime Coke. It may have jumped straight to the top in my list of favourite diet drinks. It really is tasty, so if you can get hold of one, go for it.
My rating: 5/5
