The Mystery of The Phantom Gourmet

So, I was watching "The Phantom Gourmet" the other night and lets be honest - if it's 2am what's better than watching that. I also like "TV Diner (with Billy Costa)." Both shows are the same premise - a critic goes to various restaurants and rates the service, food, price, etc. and because the persons anonymous the restaurant treats the critic just as they would treat you and I. Now I understand how TV Diner gets their critics to stay anonymous, BUT my question is...

How does the phantom gourmet not get noticed!!???

I can clearly see him - can you? Maybe I just have great eyes.
