Carnival Cruise Lines said it has begun offering premium steaks for a $20 surcharge in its main dining rooms.

The menu addition was tested on four ships and was expanded to most of its fleet in August, spokeswoman Jennifer De La Cruz said.

Labeled “Steakhouse Selections” on the menu, the aged prime meats come as a 9-ounce filet mignon or a 14-ounce New York strip steak. Diners can order a lobster with their premium steak. 

Carnival will continue offering steak and lobster as part of its complimentary menu in the main dining room. 

Each Carnival ship already has a steak specialty restaurant with limited seating and a cover charge of $35 per diner.
