I went to a restaurant a while ago (possibly in Rome... maybe Zurich..) where they served a sharing plate of thinly sliced raw steak. Everybody's dining plate was really hot so you cook your own meat on your plate. No idea what the plates were or where I can get some from, any ideas...?
One of our early microwave ovens came with a plate which you could heat for a minute or two and then cook thin slices of steak in it. Perhaps a cookshop might stock such things.
