I originally tried this product with some trepidation, as I did not care for the lemon flavored colas that came out a few years ago. I was pleasantly surprised that I really enjoyed Coke Lime. The lime flavor was subtle yet present. Coke Lime is also quite refreshing. My only issue is that it is very hard to find at places like Walgreens, which only seems to carry the diet version. I've heard that the diet version is quite good also, but I don't drink diet colas. I would highly recommend Coke Lime, I think it is one of the best of the flavored cokes.
