Food ….
No visit to South Australia is complete without a meal of King George Whiting. Have it with riesling, and remember: the best rieslings come from Watervale or Eden Valley.
Overseas visitors should try kangaroo. If you like venison, you’ll like kangaroo. It’s widely available; come up to the Mt Lofty Summit restaurant so you can enjoy the view at the same time.
Buy a box of chocolates from Haigh’s (the Beehive Corner shop in the city or the factory shop on Greenhill Road). Haigh’s make the chocolate from scratch, beginning with the cocoa beans. (Get the dark chocolate cream centres, and have a glass of Seppelt’s Original Sparkling Shiraz to go with it.)
Restaurants … combining the food and the experience …
Go to Jolley’s Boathouse on the banks of the Torrens River for lunch, or an early-start dinner in summer when the evenings are long and light. All the food is good; you need to go in the daylight so you can watch the river, the birds, the rowers and joggers.
Drop in to Café Michael 2 on east end Rundle Street in the city, for green chicken curry. It’s the best green chicken curry in town.
Indian curries: the Dhaba Hut, on Kensington Road. Magnificent.
Drive for an hour down the coast to Pt Willunga, and have dinner at the Star of Greece, a restaurant perched on the clifftop overlooking a pretty bay. When I was a kid, this was the kiosk where you bought ice creams and fizzy drinks. Now, with a few glass windows installed and a new paint job, it’s a top-notch restaurant. You might like to have your King George Whiting here (see above). Sunset views in summer are extraordinarily beautiful.
In the same neighbourhood – Russell’s Pizza, a gourmet pizza bar that occupies a series of old buildings (a cottage and two sheds) in High Street, Willunga. No licence: BYO. Only open Friday/weekends.
Cute stuff 
.....
For lovers of small furry animals: Warrawong Sanctuary restaurant where the food is OK but you get to look through the windows at dozens of bettongs, woylies and potoroos that come into the garden at night.
I suppose I ought to include the famous Balfour’s Frog Cake, which has been declared a South Australian Icon by the History Trust. They are a cute curiosity; I won’t pretend they are great cakes. It’s a little square of (rather dry) sponge cake, sandwiched with jam, with a blob of artificial cream on top, covered with fondant icing. It is supposed to look like a frog. It is so sweet, it will make your teeth drop out if you actually try to eat one. But … well, read this
