In Nancy Drew: Treasure in the Royal Tower, Nancy requests Dexter to fix her radiator in her bedroom. Dexter will fix it, eventually, but he asks Nancy for a favor in return. He requests she gets the Professor’s dinner order. After talking to Dexter, head upstairs to room 314 in the right hall. Knock on Hotchkiss’s door and ask her what she’d like for dinner. Relay this request to Dexter, who says to have her order something off of the hotel menu. Return to Hotchkiss and ask for her order change. She doesn’t have a menu, so hunt down yours, located in your room in the top dresser drawer. Knock on the Professor’s door again, then look down at the floor and place the menu there. Once she decides on an order, tell Dexter. Your last step is to tell Jacques to pull out the bag of chicken legs from the freezer.
