There is a smaller version of the burger (slightly different but close) at the HBD Lounge in the evening, so I've got to believe they would allow him to order some version of it. The one in the Lounge is smaller, as it is also paired with a duck confit "slider," but when we ordered it, they said we could get one of each or two of one, so again, I would be shocked if they wouldn't allow some sort of burger option at dinner in the actual dining room.
