Venti skinny iced green tea latte with two extra scoops of matcha.
Or… "Yes, I'd like you to liquify an alfalfa field and toss in some ice."
Surprisingly tasty. And not really alfalfa field-y at all.
Pro tip when ordering, though: It's called "matcha" not "ma-cha-cha" or "machata" which is how I mis-pronounced it.
The cute 20-something barista lady made fun of me.
