Take a fun step into culinary nostalgia! St. Louis’ nitro ice cream parlor, Ices Plain & Fancy, flash-churns ice cream using liquid nitrogen. The innovative parlor is named after the Victorian “Queen of Ices”, Mrs. Agnes Bertha Marshall, a self-made English culinary entrepreneur, writer, teacher, business leader, inventor and patent holder. She was one of the first to suggest using liquid nitrogen, or “liquid air”, to create ice cream! The owners of Ices Plain & Fancy create an eclectic experience in the historic Shaw Neighborhood with their made-to-order nitro ice cream specialties.
