I find it particularly ironic because the owner's father was down and out after World War 2 and received a loan from an American named Harry to open the restaurant. I am sure the owner realizes that the Americans who would probably visit this establishment are not financially hurting, it seems like an insult if you ask me. To me it looks like he is trying to jab at America which is experiencing some hard times, surprising considering Italians tend to like Americans, a contrast to other countries on the Continent like France and Germany.
