Rundle Mall in downtown has the best supply of shops and malls and is good for people-watching and snacking. Special buys in Adelaide include local wines, of which there are many that are churned out in nearby vineyards, and white opals that are mined in Coober Pedy.
Located in the heart of downtown Adelaide, Rundle Mall is where it's at regards shopping and eating. It is a pleasant pedestrianised arcade which stretches a fair way and is wall to wall shops and cafés. While busy, Rundle Mall never gets over the top and you can enjoy the shopping and nightlife at any time of the year.
Central Market is not far southwest of Rundle Mall and is also right in downtown. It lies between the main Grote and Gouger streets and comes with interesting food, shopping and restaurants. Central Market makes a great stop off for a bite to eat while in shopping mode.
Grote Street runs right through the middle of downtown Adelaide in the western half and is particularly good for antiques shopping. There are loads of antiques and collectibles stores under one roof here where you can pick up some fantastic South Australia items.
