Well, what can I say? You can expect what you can expect from almost any HRC in the world : good drinks, good food & great music!
Update : This outlet has long since closed and the Hard Rock Cafe Sydney is reopened at Darling Harbour
Dress Code: Smart casual is good
For a fun dinner, head to either the Hard Rock Sydney, or the Planet Hollywood. I believe they are pretty close to one another. Both are in the Kings Cross district and the Hard Rock Cafe is where I dined. It's open from Noon to Midnight and the menu ranges from $6USD-$15USD. There is a giftshop too, this is where you'll find those famous Hard Rock Sydney shirts, hats, jackets, and more.
