For the past few years, there has been speculation about a secret menu from Starbucks, and some people swear it's real. Anything from a "Banana Cream Pie Frappuccino" to a "Butterbeer Latte," to secret sizes like the "short drink" that holds 8 oz. and a "trenta" that holds 31 oz. of your favorites can be found at a Starbucks--only if you know how to ask for it. Because no one really knows everything on the secret menu, many locations won't serve up some of the signature drinks you may read about online. However, Starbucks has recently released how you can purchase their famous "Rainbow" drinks, and some other fun concoctions from most locations.

Pink Drink: Strawberry Acai Starbucks Refreshers with coconut milk instead of water, with strawberries and/or blackberries

Purple Drink: Teavana Iced Passion Tango Tea with soymilk instead of water, and vanilla syrup and blackberries.

Orange Drink: Orange mango juice with vanilla bean powder, a splash of coconut milk, and orange wedges.

Green Drink: Teavana Iced Black Tea with coconut milk instead of water, and matcha.

Blue Drink: Teavana Iced Passion Tango Tea with soy milk instead of water, and vanilla syrup.

After diligently researching the secret Starbucks menu, there are some secret drinks that Starbucks locations will definitely serve if you simply just ask for it, which goes against the misconception that you would need to order a certain drink with a bunch of add-ons or say a secret password to get something from the secret menu.
