Great Restaurant
I have never stayed in the rooms here, but they look pretty average. The location of the motel is great.
On the 12th floor, there is a revolving restaurant (only one in Adelaide), which serves great food, specialising in seafood. The price is a bit high, but you will not find a revolving view of Adelaide anywhere else while dining.
The best time to go to the restaurant is at dusk, so you can see what the Adelaide is like during light hours and then what it is like after dark. I think it takes about an hour for a revolution.
