Gen Z, which includes those currently between the ages of 18 and 24, is an important demographic for restaurants.

"The earlier you can engage with a consumer, the more potential you have for building loyalty and building frequency over the course of more years," Robert Byrne, director of consumer and industry insights at the restaurant consulting firm Technomic, previously told CNN Business. It's hard to develop loyalty "once somebody's past that window," he said.

But Gen Z is less interested in dining out than other generations were at their age, making it even more important for restaurants to try to grab their attention.
