I have read that you are not limited to the small choice on the card
for the room service breakfast. You can "write in" any items you wish.
There was a further recommendation that you be very specific, however.
E.g.: Rather than "bacon" say "three strips of crisp bacon" or rather than
"cereal" say "Kelloggs corn flakes with Half and Half cream and blueberries with sugar"
Of course, you should plan on tipping your attendant at the time of delivery.
