# The week's lunch menu

> The lunch of each day of the week starting on the Monday `week`, derived from the regional seed, the house's current choices and the routine's trips: a trip covering a day's lunch (by 12:00) shows the day as `trip` and beats any choice. `alternatives` are five dishes, the dish that left a day among them. `suggestions` are the ingredients of every day eaten at home, one row per name, leaving out names open on the list; by first date, then position in that day's dish.
