Tonika is the name and bitter soda is the game! I’m not sure why Japan felt the need for a bitter soda, but, being curious (and apparently a masochistic) I decided to try it out.
It’s not just unsweetened soda…when it says it’s bitter, boy, is it bitter! It got to the point where I couldn’t drink it, my husband (who has a cast iron stomach) wouldn’t finish it, and it ended up being poured into a plant as a science experiment.
The plant is still alive by the way.
