CHICAGO — Want to churn custard and flip ButterBurgers at the city's first Culver's?

The soon-to-be-built restaurant at 4939 W. Irving Park Road will host an open interview call for potential employees from 2 p.m. to 6 p.m. Wednesday at Austin-Irving Public Library, according to a Monday Facebook post from the Six Corners Association.

The post included a photo showing a completed concrete foundation for the eatery, nearly three months after excavation work began on the site in July. It also predicted an opening in December, a month later than was announced this summer.

A spokesman for Culver's confirmed the December projection Tuesday.

The drive-thru restaurant in the Six Corners Shopping District is one of three new Culver's outposts set to open around the city "hopefully within the next year," CEO Joe Koss said after the July groundbreaking.

The chain still is trying to secure a lease for a location in Bronzeville, and the fate of a long-promised Wrigleyville branch is tied to a larger development planned for 3500 N. Clark St., the CEO said. If the Portage Park location opens by the end of 2017, it will likely beat them both to service.

The new restaurant is part of a $16 million redevelopment set to transform the 4900 block of West Irving Park Road.
