Menu engineering involves strategically designing a restaurant menu to maximize profits through menu psychology techniques. Some key strategies include highlighting popular and profitable items in the "golden triangle" areas at the top of the menu where customers' eyes first look. Descriptions can appeal to customers' imagination and nostalgia. Including photos increases sales. Prices ending in .95 rather than whole dollars and limiting choices can also influence customer purchases. Ongoing testing and revision is important to continuously improve the menu's performance.
