@FallenRedNinja Adelaide is party town during Fringe, so many shows to see, you never get to everything. This does not mean things are open late though. The major supermarkets all close at 5pm on Sat/Sun and usually 7pm-9pm on weekdays. If you need anything after that time, its 24/7 convenience stores only and those are mainly attached to petrol stations. Coffee shops are everywhere in the CBD so you can get a caffeine fix very easily (up to about 3pm) and the Adelaide Central Market is always good for a visit.

@FallenRedNinja The Botanic Gardens in CBD are extra pretty at the moment, they are full of big, beautiful glass sculptures which are free to view during the day. The 2 big venues (Garden of Unearthly Delight and Gluttony) has some good stuff, but the Courtyard of Curiosities at the Migration Museum has a really eclectic mix of shows that more people should see.
