No, all food critics aren't pure as driven snow. They're human. But I think the good ones try as hard as they can to remain hands-off and objective and, most of all, anonymous. I work on a weekly basic cooking column with a restaurant chef and occasionally spend a night working in the kitchen of the restaurant to feel the "rhythm" - I do this with the blessing of my newspaper. Before I did, though, I made it clear I would never, ever review anything he did from that point on. Food critics don't spring forth full-grown. Most of us had prior lives and ran across chefs in that capacity. If I review a restaurant where I'm recognized or known, I always tell my readers so they know where I'm coming from. (Some of my compatriots disagree on this, feeling readers think its snotty to mention being recognized or known.) On the whole I go out of my way not to be known or recognized. I think I'm doing a disservice to my readers if the only experience I can report on is what the critic gets instead of what is dished out to the average Joe. And, of course, there's disagreement in the critics community about this. Yet I think the tide has turned, strongly, toward anonymity. I tell people than anyone who shows up in a restaurant and announces he/she is a critic should be shown the door. Either he/she is a fraud or he/she is so compromised the review won't be any good. The Association of Food Journalists has suggested guidelines for critics. (I chaired that committee.) You can read what AFJ has to say by going to: www.afjonline.com.
