A guilty pleasure is a guilty pleasure. I love coffee and tea. Unfortunately, I have been avoiding coffee because of acid reflux.
My current guilty pleasure is a Venti Non-Fat Green Tea Latte (Starbucks).

From the Starbucks website: An intriguing blend of premium green tea, soothing steamed milk and delicately sweet melon.

If you love coffee, you should try (if you haven't yet) Peet's Coffee.
