Most Expensive Sandwich

I don't think I could differentiate between this and a much cheaper sandwich. I wonder if it's a "the emperor has no clothes sort of thing."

Hungry shoppers are being offered the chance to eat a gourmet sandwich, but
the £85 price tag might be too much for some to swallow.
The ingredients of the sandwich are: Wagyu beef, fresh lobe foie
gras, black truffle mayonnaise, brie de meaux, rocket, red pepper and mustard
confit and English plum tomatoes.
