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.

The amount of sugar in these drinks is reportedly comparable to that found in a Reese's peanut butter cup. Eight specific protein drinks are mentioned in the lawsuit.

Further details about the lawsuit and the allegations against Starbucks are available from the source.
