I am about 1/2 way through it... it is the Bourdain voice we have all come to expect. He is brash, droll and punchy. And that's just the intro!
In all seriousness, he takes recipe writing to a 'different' place; his descriptions are flavored with fire and a bit of spite, now and again. He holds nothing back and shows off for the camera. But, again, that is why we have read Kitchen Confidential with such gusto.
His passion, his style, his rhetoric is not for everybody. And that's a good thing; for those of us that relish his fantacism, his piquant style is a pleasant foray to never, never land.
