To me this all seems little more than getting some free publicity.
Am not, have never been, and at my age will never be a professional chef.
And know little about cost of food, well, the stuff served in restaurants anyway.
But I don't understand how anyone could make any worthwhile cash with a 134 lb burger on a fifty lb. roll for $350. And one must add in the cost of the cheese and bacon.
Of course one also has to pay for all those hands to make the beast.
I have nothing against publicity stunts. And the place might be happy to make one or two just to get the media exposure.
But basically no one is going to go for it. Unless it is a local company doing it to put on an interesting party for their employees.
Before criticizing a person, walk a mile in his shoes - then you are a mile away and you have his shoes!
