Ted Drewes has been selling frozen custard for over 80 years and has become a popular treat for St. Louisans and tourists to enjoy after visiting the Arch, the Fox and Muny Theaters, the St. Louis Zoo, or a Cardinal’s baseball game. Along with the delicious hot fudge sundae, Ted’s “concrete” has been the most popular treat at the custard stands. The concrete, which was created in 1959, is a malt or shake so thick that it is served upside down.
