Anyone watch Kitchen Nightmares? It's on Thursdays at 9. Great stuff. Gordon Ramsay, British celebrity chef, visits failing restaurants and turns them around. The restaurants usually have some massive sanitary problems, or the cooks can't cook, etc. It's worth watching just to see Ramsay explode at the owners after finding out the kitchen's full of roaches or the cooks don't know how to make rice.
The UK version is apparently less confrontational and more about the inner workings of a restaurant, which also sounds pretty neat.
