Read cost and margin together

A single low margin item might be fine, but a low margin bestseller is a problem. Pairing margin with sales volume reveals the real drag.

The dishes to watch are high volume and low margin, since they move the most money the wrong way.

Frequently asked questions

What is menu engineering?

Menu engineering plots each dish by popularity and profitability to classify it as a star, plow-horse, puzzle, or dog. The grid guides which items to promote, fix, reprice, or cut.

Why can a best-selling dish still hurt profit?

High volume magnifies a thin margin. If a popular item barely clears its cost, every extra sale adds little profit while consuming labor, prep time, and menu space that a stronger dish could use.
