Chris Cosentino is a chef whose claim to fame has been his work with offal. His restaurant in San Francisco is called Incanto. I've eaten there, its really good.
I became interested in Mr. Cosentino through a friend who turned me on to his now defunct Food Network show Chef vs. City. Watch this video because if nothing else the guy will charm you with his passion. Unfortunately, Chef Unleashed was not picked up, so it stands as a singular document to respecting the food the rest of us thoughtlessly put in our mouth.
He'll have a cookbook released in March 2012.
