The two main dining rooms never charge. The buffet, outdoor grills, and Blue Laggon no charge either. One or both of the main dining rooms are open for breakfast and lunch as well.
You are in luck. They just started new menus for the main dining rooms. Each of the 2 will have its own different
menu. They stay the same with the addition of a chefs special each night like a restaurant on land. The good news you get the option of a couple of Lobster dishes every night, prime rib, well take a look for yourself
Here is a link to last week's Freestyle Dailys giving you a taste of what will be happening onboard.
