Adelaide cops a lot of crap but its actually very easy to drive around and there's really nice and cheap food on O'Connell Street in North Adelaide, I always stay there when I visit, its nice being able to walk out your apartment having choice of about a bazillion cafes and restaurants where mains are sub $40 unlike Melbourne.
Tony Tomatoes there does one of the best Pizza's I've ever had.
Casino leaves a bit to be desired though
Yopu can tell the difference in 'accent' between people from Adelaide and Perth compared to Melbourne and Sydney, they sound different.
