If I had to guess, they probably asked the server if they could substitute scallops for the lobster tail on the "Grilled Filet Mignon or Black Angus New York Strip Steak with a Butter-poached Maine Lobster Tail" entree. In the (long ago) past, one of my family members was able to substitute crab cakes for the lobster tail (she has an allergy to under-cooked shellfish), so perhaps they allowed this diner to substitute the scallops from the "Pan-seared Georges Bank Day Boat Scallops" entree. I don't see scallops and steak as an entree listed on any of the menus posted on Allears.net, wdwinfo, or DisneyWorld.com.
