About Us

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

Our Story

Where It All Began

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.

“You don’t need a silver fork to eat good food.”

“Best in Charleston”

“Simply best in Charleston. This is a small gourmet shop with a lot of love in their food. The sandwiches/salads are the best. I always get some chicken salad to go (slight taste of ginger taste is crazy good). Last minute dinner party, these guys cater as well. ”

“Great little find!”

“Great little find! My husband and I shared a sandwich and salad, perfect! I think it was the owner who helped us. He was very kind in giving us a few options since it was obvious we had never been.”
