While at the Dallas Anime Club this afternoon, I tried Vanilla Coke. It was definitely less-bad than I expected it to be — sure, the vanilla flavor was there, but not overwhelmingly. In fact, if you were to guzzle it, you may not even notice that it wasn’t regular Coke.
Interestingly, this reporter had just the opposite experience:
The verdict? Not so thrilling. Vanilla is prevalent, for sure. In fact, it's so present that it's all you taste. It coats that delightful, battery-acid kick Coke is known for.
At any rate, I think I'll stick with non-sugared soda made with Splenda (“Made from sugar so it tastes like sugar”). Seriously, if haven't tried Diet RC/Diet Rite, give them a chance (both use Splenda, but the latter has no caffeine). They don’t taste exactly like Coke but, then again, regular RC doesn’t taste exactly like Coke either ;).
