What is food called when it is visible to customers before purchase?

Food that is visible to customers before purchase is typically referred to as "Food On Display." This term encompasses any food items presented in a way that allows potential buyers to see them prior to making a purchase decision. This display is often used in restaurants, grocery stores, or delicatessens to entice customers through appealing visual presentation.

Having food on display can engage customers and showcase the quality and freshness of the items being offered. This practice not only enhances the visibility of the products but can also encourage impulse purchases as customers may be drawn to the aesthetic appeal or the desire to try what they see.

The alternative terms described in the provided choices have different meanings: for instance, food sampling relates to the practice of offering small portions for customers to taste, showcase items often refers to a specific selection of products featured prominently, and menu specials pertain to specific items on a restaurant menu that are offered at a reduced price or are unique to that day. "Food On Display" most accurately captures the concept of making food visible for purchase.
