Seen on a recent menu. They reprinted it to include this information; they could have reprinted with the actual higher prices, and if they ever intend to drop the surcharge they’ll have to reprint again, so the only motivation seems to be to disguise the price hike/keep it out of customers’ minds as they are ordering.
