It's not a soda, but it caught my interested, so here we are. The can says it's an energy drink. Fortunately, it doesn't taste anything like an energy drink. It tastes like "chocolate drink", which means it's not quite chocolate milk. Even though it does has milk in it, it's skim milk, so it might as well just be water.
If you've ever had a Yoohoo!, this is pretty much that, although with a thicker consistency than a Yoohoo! Overall, nothing special.
