Saturdays are a big day to dine out, but an increasing number of people are opting to stay home and order in. According to a recent study, the number of deliveries is up 10 percent overall. The drive is fueled in large part by the rise of apps like Grubhub, Seamless and Uber Eats, which take the orders online for the restaurants and deliver the food. Those restaurants have taken notice, and are even changing the way they do business. Dana Jacobson reports.
