Sunday Lunch in Adelaide
Depends on budget and time of day
Locavore - http://www.thelocavore.com.au/. Australian tapas. Nice after a morning drive in the hills
The star of greece - pt willunga
Get a table by the window (lunch). great after a drive through the McLaren Vale wine district
try estia down at henley beach greek meze style eating but book a table out side to be sure of getting in ,sundays are busy great food great wine list .after eating try a walk along the jetty and then a coffee at cibo or a drink at bacchus, a very civilzed way of ending a perfect sunday
The Pot on King William Rd, Hyde Park. On other days they do fantastic wine and tapas, but on Sundays I believe they have a set menu Sunday lunch. I admit I am yet to go on a Sunday as I work but I wish I could, from what I recall is reasonably priced and very nice.
Also, Windy Point has recently launched a Sunday breakfast/brunch/lunch menu which sounds fantastic, once again great food ordinarily so I assume the same for Sundays.
