86 (to 86 an item)
To 86 an item is kitchen and floor shorthand for a dish or ingredient that is sold out or pulled from service and can no longer be ordered.
When a kitchen 86s something, it is off. The word is old restaurant slang for out of stock or otherwise unavailable, and it moves fast from the line to the servers to the POS so nobody sells a dish the kitchen can no longer make. To 86 a bestseller mid-rush is a small failure with a real cost: a guest who wanted it settles or leaves, the server has to circle back to the table, and the check often lands lower than it would have.
An 86 is almost always a forecasting miss upstream. You prepped too little of the thing that sold, or over-bought something else that is now heading for the trash, and both are the same problem seen from opposite ends: you did not predict demand well enough to set the right pars. Frequent 86s on popular items also quietly cap your sales and drag your Average check, because the highest-margin plate is the one you ran out of.
This is exactly what demand forecasting is for. AI that reads your own sales history by day, daypart, weather, and local events sets prep pars that track real demand, so you neither run out of the hero dish nor waste the ingredients for the one that did not sell. Forecasting vendors market accuracy gains like 35% more accurate over traditional methods, and an AI pastry-demand model for a multi-cafe operator improved ordering accuracy by 8% accuracy gain in its first month.
