The Thrillest picks correctly for Missouri in its listing of the best doughnut shops in each state.
For Missouri, it picks the Donut Stop on Lemay Ferry Road (at the intersection of Telegraph and Lemay Ferry Road).
I’ve eaten many doughnuts from that place, as it was right down the road from my sainted mother’s house, and she’d often pick up a couple for us on Sunday mornings when I’d come to visit.
