This is what the description said:
Dining is a new take on the main dining room, reimagined to give you a culinary experience at sea as vast, varied and eye-opening as dining in the world’s most cosmopolitan cities. Discover the culinary curiosities of Wonderland Imaginative Cuisine. Savor the handcrafted fare and craft beers of Michael’s Genuine® Pub. Experience it all with our signature personal service as we elevate the concept of dining at sea. When Anthem launches this April, you can choose one of two different ways to experience Dynamic Dining.
Dynamic Dining Choice gives you the freedom to pick and choose your restaurants and dining times each day and night. Our unique venues feature menus that change throughout the cruise, with guest favorites and new specialty dishes to ensure everyone at the table will find something they love.
Dynamic Dining Classic is a new option for those who prefer the traditional main dining style with the same dining time each night, with the same wait staff and dining companions throughout the cruise. Dynamic Dining Classic is available on a first come, first serve basis.
