T. Marzetti produces numerous salad dressings, fruit and vegetable dips, frozen baked goods and specialty brand items.
"[3] Marzetti's became a local favorite especially among Ohio State University students, and grew to become a four star restaurant.
Customers particularly enjoyed Teresa's Johnny Marzetti, a pasta dish named for her brother-in-law, as well as her homemade salad dressings.
By the late 1960's, the company built a dressing production plant in Columbus' Clintonville neighborhood on Indianola Avenue.
After Teresa Marzetti's death in 1972, the restaurant closed, but the company and factory have continued on to this day.
