We recently went for dinner at Inamo restaurant in London, where interactive touch-sensitive tables take your order. Each table has an overhead projector and a mouse trackpad, so your dining surface is effectively a PC monitor. You can customise your 'tablecloth', play a videogame against your companion and order a taxi to get you home.
When you're ready to order, you can browse the menu, with each dish projected on to your place setting. When you've chosen, you can even see a live webcam feed of your chef at work. The restaurant's founders say the concept evolved from the simple idea of 'Wouldn't it be cool if you could just hit a button and a waiter brought you another beer?' Watch our video for more.
