Caramel Frappuccino @ Starbucks Coffee

Got bored with the green tea frappuccino and hojicha, so this time I got the Caramel Frappuccino.

I assumed there was no coffee in it, but it tasted bitter.
After asking the barrister it turns out that you need to tell them beforehand.

But overall, the drink was quite nice and not too sweet and the caramel was nice and strong.
