Featured Vendor Series: Square Onion

"Before Cory 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, Cory'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 Cory, you'll see him there every day 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."
