O'S Restaurant sits near the Vaal River in Parys, with tables in a garden and a separate cocktail bar for adults. The kitchen serves pizza from a stone oven, along with steaks, seafood, and South African dishes like bobotie. The cocktail bar, called Die Plek, is on a private deck by the river and admits only guests over twenty-one.

The menu includes breakfast until mid-morning, with options like scrambled eggs on ciabatta or a traditional pap and mince dish. Later in the day, the kitchen prepares rump steaks, spare ribs, and oxtail, or you can order a pizza with toppings like biltong or seafood. The bar serves local wines, brandies, and cocktails, including frozen daiquiris and mojitos.

The garden has views of the river, and some tables are set close to the water. The restaurant has been open since 2005.
