What does "86" mean in restaurant lingo?

In restaurant terminology, "86" specifically refers to an item that is out of stock or unavailable. This slang helps staff quickly communicate essential information about the menu to each other during busy service times. When a dish or ingredient is no longer available, a server will often announce, "We 86'd the salmon," letting everyone know that it cannot be sold until it is restocked. This term is crucial for keeping service smooth and ensuring that customers are informed about their options without delay.

In contrast, recommending a dish, offering discounts, or indicating featured menu items does not fit the definition of "86." Each of those terms has its own specific phrasing within the culinary industry.
