Ted Drewes has been making frozen custard at its Chippewa Street location on Route 66 since 1941, with the original stand having opened in 1929 in a different part of town. It is a St Louis institution: long queues in summer, the same paper-cup menus, and the famous "concrete" — custard so dense the cup is handed to you inverted.
The product itself is excellent — denser and richer than soft-serve, less icy than ice cream, with a long menu of mix-ins ranging from the classic chocolate chip to seasonal pumpkin. Cash and card both accepted. The Grand Avenue location is open year-round; Christmas-tree sales take over the parking lot in December.
