Hard Rock Cafe, London

If you like American burgers or rock memorabilia this will be on your tourist route, so don't resist. And anyway, this is the world's first Hard Rock, so there's some value in that. Be warned though, this venue is always busy so be prepared to queue. Merchandise is also on sale so now is the time to pick-up some tacky souvenirs for your mates back home. The American menu is actually quite good, and the perfect place to satisfy a craving for a plump, char-grilled burger with a heaped portion of fries. Other healthier choices are available, of course, like salads and veggie burgers. And don't forget to leave room for those extra-sweet desserts!
