“The difference between online ordering and offline is that most restaurants tell us orders are bigger and higher," says Eat24's chief marketing officer Amir Eisenstein. “For example, if you order a pizza over the phone you'll just tell them to bring an XL pizza and a Coke. But when you go online, you see the whole menu. All of a sudden, people order appetizers, ribs, salads, and stuff they don't normally order over the phone. They have more time on the menu, they spend more time on the menu, and they order slightly more items than over the phone.”
