Established in 2018, ​The Flour Store is a licensed cafe in Port Noarlunga serving breakfast and lunch as well as a selection of cakes and beverages  Wednesday to Monday.

The Flour Store (or “Old Barn” as it was originally called) was built in 1845 by the Mortlock family. The building was used as a grain store originally when the wheat trade was booming. The building has served many purposes over the years including a sweet shop, grocery store, pet shop and most recently a surf store. The building has been lovingly restored and was renamed to honour its heritage.
