In Adelaide there is McDonalds, Hungry Jacks (owned by Burger King US. Burger King in Australia is actually a different chain btw Cub and I think exists in Melbourne.)
There's also KFC, Nandos (Mexican Food, very big here).
Pizza wise we've got a war going on between Domino's, Pizza Hut and Pizza Haven, they all seem to be doing pretty bad.. lots of closures across the board, Pizza Hut shut down all its eat in restaurants, they are now vandalized by hoodlums, they only have 1 actual restaurant which is their biggest.
We've got Subway here too, Donut King, I think theres a Crispy Cream here too, trying to find out where the fork it is since the guys from work keep bringing them in. We've also got a few Dunk'n Donuts.
We've got Wendy's here too.
Starbucks just moved in not that long ago.. Very scared

Adelaide is too small for a starbucks IMO, plus Hudson has like 3 branches right next door to each other.. next we'll have a bloody coffee war
We've got a fish fast food chain called Barnacle Bill's here in Adelaide, we've also got a place called Fasta Pasta which does take away food, their stuff is pretty exceptional.
We've got a lot of Wok places here, Wok in a box, Quick Stix, ect ect.. though they all taste like crap

- blame that on my stomach hating anything Eastern.
There is also a Balfour's bakery in Adelaide, make some really nice food there, they shut down their main restaurant 3 years ago which is a pitty but they've got a place near by my work still. There's also a Villie's here in Adelaide too which is always packed with people, some of the best baked food I've ever had.
There's also this place called Australian Pizza house, they're like a Niche Pizza house, excellent prices. They make specialty pizzas, but they taste so good and are really cheap if you don't get anything too exotic.
There are also plenty of local places to get fast food at. The guy that makes my pizza around the corner from my place is a bit like Louie LaMintz

.
But by far the best food in Adelaide will always be a pub meal
