A lawsuit has been filed against Starbucks, alleging that certain protein drinks are mislabeled. The drinks in question are labeled as "sugar-free" on cafe menus. However, it is claimed that these drinks may contain significant amounts of sugar, potentially more than what is found in a Reese's peanut butter cup.

The lawsuit specifically mentions eight protein drinks that are allegedly mislabeled. Further details about the lawsuit and the claims against Starbucks are available from the source.

The allegations suggest that customers may have been misled about the sugar content of these protein drinks, which could be a concern for those monitoring their sugar intake.
