Starbucks reveals "secret" menu in coffee chain's app. Here's what you'll find.

Starbucks' "secret" menu is no longer hidden from the public. 

The coffee chain on Monday introduced previously hidden offerings for Starbucks rewards members in its mobile app. The menu allows customers with rewards accounts to access drink combinations not listed on its regular menu. 

Starbucks is offering four new drinks via its app: Cookies on top; a dragonfruit "glow-up"; lemon, tea and popping "pearls"; and a white mocha shaken espresso.
