Imo's Pizza

Imo's Pizza is an American chain of pizza restaurants headquartered in St. Louis, Missouri. As of 2020, the company says it has more than 100 restaurants and stores in Missouri, Illinois and Kansas.

The chain was founded by Ed and Margie Imo in St. Louis in 1964.

The chain is known for its version of St. Louis-style pizza, which is common in the area and features provel cheese—a combination of cheddar, Swiss, and provolone with a low melting point and gooey texture. The restaurants also sell salads, submarine sandwiches, and desserts, the last including ones that can be made in a pizza oven.
