People say Hard Rock Cafes are lame and over priced, while others have a bad experience with food served at Hard Rock Cafes. In cities like Jakarta, Bali, and Beijing it’s not just about the food, its one of the best night clubs in town. The one in Beijing rocks! In south-east Asia they are relatively cheap. If you want to find an interesting menu, Hard Rock Amsterdam is the best place to be. Gold coast (in Australia) and Fukuoka is known for cheap drinks and decent food. It seems that the one in Seoul is the worst, if you consider price, Vat tax, patrons and location; also it might be because it’s overrun by Kangnam poseur Koreans.
You can see some Hard Rock T-shirts, shot glasses, and pins. The majority of people whom you will find in Hard Rock Cafes are Visa Runners. They really get a lot of visitors who are on a visa runs.
