I've only been to three hard rock cafes so far, and one of those is in my home country of the UK. The others were LA and Copenhagen.
The one thing I love about the Hard Rock Cafe is that the staff always seem to enjoy their jobs, and they give better, more friendly service than most 'posh' restaurants I've been to.
I don't collect the T-Shirts, yet, as they seem so expensive, but I think I might start...
I didn't realise there was a HRC in Tokyo! I can't wait to go there now
