When a handful of proteins and specialty items carry most of your plate cost, an average tells you almost nothing. Category-level COGS shows a change in protein or seafood cost on its own, so you can adjust a dish or a supplier rather than the whole menu.
Wine and spirits inventory can represent a serious share of working capital, and beverage margin behaves nothing like food margin. Tracking beverage cost as its own category — separate from food, separate from labor — keeps a strong bar from masking a soft kitchen, or the reverse.
Fine dining carries a larger team per guest by design. What matters is whether labor is holding a consistent relationship to revenue as covers and check averages move. DishBooks reports labor inside prime cost so that relationship is visible period over period.
Fine dining buys from specialty purveyors, farms, and importers rather than one broadline distributor, which means more invoices, more formats, and more coding. DishBooks reads them as they arrive and codes each item to its category once you've mapped it. New vendors and new items get flagged the first time they show up, so the list can grow without the work growing with it.
