Modern Market guests aren’t especially prone to ordering dessert. But the fast casual was looking for ways to increase check averages, especially at dinner, says co-founder Anthony Pigliacampo, and hiking prices wasn’t the answer. So it looked to expand its dessert program—formerly limited to cookies—with a sweet pizza. “It was an opportunity for us to build incremental sales,” says Nate Weir, director of culinary ops. Six weeks in, the strategy is working: Weir says the pastry now makes up 4% of total pizza sales.
