Mario’s Restaurant & Pizzeria



Mario Simoni quit his day job at General Motors to start a new life in the pizza business.

marios-mariosimoniMario Simoni worked days at a General Motors plant and nights at a friend’s pizzeria when he decided to strike out on his own. An Italian immigrant, he opened Mario’s Restaurant & Pizzeria in Flint, Michigan, in April 1963. He developed his own recipes and served fellow Italians in the area with a simple menu (pizza, pasta and sandwiches). He offered late-night hours for factory workers, opening from 4 p.m. to 4 a.m. each day. “It was a struggle at first, with 12-hour days,” recalls Frank Simoni, Mario’s son and current co-owner with his brother Sergio. “My brother Jerry and I basically grew up in the business just to be able to spend time with Mom and Dad.”

In the ’70s, Jerry and Frank went to work for the family business—now with a full bar and an expanded building—after graduating high school and fully took over the business in 1981, while Sergio, Mario and Mario’s wife, Margherita, moved to California and eventually opened up a restaurant in Escondido. But the family returned to Flint in 1997, and Sergio got involved with the original business, while Jerry struck out on his own to start a new venture.

From sponsoring local teams to dipping their toes into social media (Frank’s daughter started a Facebook page for the restaurant in 2013), the restaurant maintains a balance of honoring the past while adjusting for customers’ changing demands. Part of the restaurant’s success has involved its dedicated staff and the constant presence of at least one family member, adding a touch of personal warmth that touches every customer. “The pizza business takes hard work and dedication—it’s not the work that’s hard, but the hours you put in,” Frank muses. “But, as I tell my staff, when people come in, we want them to feel like they’re coming to our house for dinner.” –Tracy Morin

    Mario’s was a special treat for our family when I was growing up(60’s-80). My pops favored the spaghetti and I lived for their pizza. Great memories.

    My wife, who was from Grand Blanc, will tell you that Mario’s has the best Antipasto Salad anywhere. She orders it every
    time we are in town.

    Hey Frank, you look exactly the same as in the 70’s Lol. You are holding up very well. Lots of great memories.
    From baking cookies in the oven to your dad throwing loaves of bread at me and swearing at me in Italian when I screwed up. Good to see that Mario’s is still rolling along. Keep trying to catch you there when I come up from Florida every year but keep missing you. All the best.
