The Berlitz Complete Guide to Cruising and Cruise Ships has labeled Royal Caribbean's food as the worst of the major cruise lines, giving it five out of ten stars for its cuisine.
Book author Douglas Ward was particularly harsh on Royal Caribbean's dining room, afternoon teas and wine lists as being the worst. He did concede that Oasis of the Seas managed to earn a rating of more than six out of 10 in only one category: informal dining/buffet.
