If you haven't been to St. Louis Frozen Custard, go already.It's frozen treats are almost as good as their service. Custard is available in staple flavors such as chocolate and vanilla and featured flavors, too. Design your own sundae or grab a slice of heavenly cheesecake. On the lighter side, try a frozen fruit smoothie. Eat outside or even drive-thru. The parking lot accommodates buses for large groups. Open year round.
