A food item called the "Land, Air and Sea" can be ordered from the McDonald's secret menu, with one outlet describing it as a Filet-O-Fish order that is not well-liked. However, the nature of this item is unclear, as other outlets mention it in the context of boosting protein in a burger or as part of a breakfast hack. It appears unrelated to other uses of the phrase "Land, Air and Sea", which is also referenced in various non-food related contexts.
