This is the only fast food chain item outside Popeye's Fried Chicken that has a place in my life.
It is not particularly great iced coffee. It is not delicious in any way that I understand. But on a hot day when I'm thirsty, or after exercise, it's deeply and reliably satisfying in a way that no other drink is. It hits every note I need.
Go ahead. Flame me. Hate me.
