US Burger chain Carl’s Jr and South Aussie icon Cafe de Vili’s are set to open new locations in Adelaide’s northern suburbs.

The popular eateries would be part of a $5 million development featuring the two food outlets and a new Ampol service station.

Plans for the development have been lodged with Playford Council.

The Carl’s Jr restaurant would be the company’s fourth in South Australia, while the development would see the opening of the third Cafe de Vili’s site.

The development is proposed for a vacant site opposite the Elizabeth Magistrates Court on the corner of Main North Road and Elizabeth Way.
