The article says $100 per serving. Unless we are eating at the Big Texan in Amarillo, a serving is about 6 to 8 ounces of steak, so it is more like $200 per pound.
According to the original article the wagyu steak was not an entre but was served as hors d’oeuvres. It still is wretched excess. Might be OK for a state dinner if hard times were not upon us.
