Hugely popular sandwich chain Potbelly has its sights on San Diego. Eater got confirmation from the company that it is “actively looking” in the area. Earlier this month, Potbelly announced plans to open four locations in Orange County. Chris Birkinshaw, head of development for the brand, told us that there could be at least five shops opened in San Diego.

First founded in the 1970s, Potbelly specializes in well-stuffed submarine sandwiches that also can be ordered as “skinny” options that come with a third less meat and cheese. Since launching in Chicago, the sub shop has since spread to over 450 locations across the United States.

Birkinshaw says that the company is currently seeking a single multi-unit franchisee to operate the entire San Diego market though there is no specific timeline for Potbelly’s entry here. He shared that the sandwich shops, which range in size from 1,800 to 2,400-square-feet, could also include some versions with drive-thru windows.
