My point on the other thread was, French names are pretentious if the product can't back up the name. The name of the dish had better reflect the authenticity and the quality the name connotes. If it does not, it meets the dictionary definition of "pretentious."
An airline like UA is likely to come off as pretentious if it uses a French name to describe a meal, because it will likely be unable to deliver. Violist seems to agree.
