(11:12 a.m. EDT) -- Dinner at Carnival's popular steakhouse restaurant will now cost $3 more for adults and $2 more for kids, as revealed today by the line's senior cruise director and brand ambassador, John Heald, on his Facebook page.

The new cover charges -- $38 for adults and $12 for ages 11 and under -- will go into effect around September 20. However, Heald said the old prices would be honored for those who booked beforehand.

While the menu will remain the same, one new item diners will notice is the cheesecake, a dessert that previously had been removed from the menu but is being added back due to popular demand. The cover charge includes an appetizer, salad, entree with a choice of sauces, a selection of side dishes and a dessert (or cheese plate) with coffee/tea. Heald cited higher food costs, particularly of prime beef, for the cover charge increase.

Steakhouse selections available in the main dining room for an added fee will remain $20. Children staying in Family Harbor cabins on the line's Vista-class ships will be able to dine at the steakhouse for free.

Carnival's steakhouse is one of its few specialty restaurants that cost extra. The price hike is the line's first in five years.
