Starbucks' drink menu is changing. Here's a list of what it's removing and why.

Coffee giant Starbucks is shaking up its drinks menu, removing 13 "less popular" beverages from the list of offerings to help streamline operations and move customers through stores more quickly, according to the company. 

The move comes as the company also plans to cut 1,100 workers as part of a turnaround plan CEO Brian Niccol hopes will help revive the brand which has suffered from a series of quarterly sales declines.
