Soliciting commentary on patented process

Ol' FuwaFuwaUsagi is having a hard time getting his hands around a patented process, in particular in terms of a consumable. When I think of a patent I think of a method usually in manufacturing, a design, or equipment what I don't think of is food preparation that is not equipment specific or requires a special mix. So if I come up with a way to make a better omelet, or better fries, or a better burger is it really patentable, sans unique equipment? I mean if my secret it to dip my burger in egg white, deep fry for 15 seconds, then grill is that really an enforceable patent, and what point does it serve in obtaining such a patent other than marketing hype? You could duplicate the above with egg substitute, a pressure cooker etc. I bring this up because some restaurant concepts claim a patented process. As a matter of practicality it seems this would be more marketing than a manifestation of reality.

I understand that when you apply for a patent the theory is it is reviewed in terms of viability, practicality, and merit. However a quick review of patents issued will show you that the Government is as misguided in this attempt as they are in most endeavors (National Parks the rare exception)

Thoughts? Does anyone know of any patented processes in restaurants that effectively eliminate competitors?
