Someone with a bit more time on their hands than me (and a decent video camera) might like to take a shot at creating non-verbal restaurant reviews on YouTube. I imagine shots of the restaurant from outside, shots of the menu, the staff (suitably anonymised if required), the food and a thumbs up or down at the end. It would be an interesting gimmick.

PS - It might not last long, though.
PPS - Still, even one or two would be cool.
