It's hard to overstate how enormous Domino's is. It's the largest pizza chain on the planet with about 20,000 stores worldwide. In 2022, its global retail sales reached $17.5 billion. Love it or hate it, Domino's provides a consistent product that's easy to order and track. And the restaurant has wisely expanded its menu to include wings, sandwiches, dips, desserts, salads, and even pasta.
