Forget the article; go to an actual Panera. The amount of caffeine is clearly labeled right under the name of the drink. To be fair, their drinks contain way too much, but you can't say that they don't already make the label clear and easy to interpret. People are idiots who don't read the label beyond the "lemonade" part.

"Plant based and clean with as much caffeine as our dark roast coffee." is the full quote. Then, it lists the specific amount of caffeine for the two sizes.

You can argue it should have a more eye-catching and cautionary presentation, but it's disingenuous to say it wasn't clear and explicit.

contained as much caffeine as the restaurant’s dark roast coffee

That part. Though I don't think people realize how much caffeine is in their dark roast coffee. Because it is more caffeine than multiple energy drinks for the same volume. There's a reason a standard cup of coffee is like 6 oz instead of 20 oz.
