Square Onion

A gourmet corner shop in the Ion Neighborhood in Mt. Pleasant, SC

Before Cary Zapatka became an owner of Square Onion in 2003, he had honed his love of food, recipes and service in some of Charleston’s best restaurants. Since the start, Cary’s vision was to provide high quality, simple but flavorful meals in a casual neighborhood corner shop and deli. Now 15 years later, the Square Onion continues to be a Charleston favorite for sandwiches, soups, salads, casseroles and more. As for Cary, you’ll see him there everyday keeping his hand in the day-to-day operations to ensure the standards for the high quality food and experience are consistently delivered to his patrons at the Square Onion.
