The growth in the restaurant industry is coming from those who are dining at home.

USA Today reports:

Micha Magid would prefer that guests grab a table to enjoy the sweet corn fritters, chicken wings and "brontosaurus" ribs served at Mighty Quinn's Barbecue, his restaurant chanin.

But so many diners want their food delivered to their front doors instead, the eateries have to carve out valuable space solely dedicated to fulfilling those orders.

"If we have our preference, everyone would come to the restaurant,'' says Magid, one of Mighty Quinn's co-founders. "You get a much better experience when food doesn't have to travel for 15 minutes. It's hotter and better . . . But if someone wants to stay home and get great barbecue, we want to deliver that.’’

The growth in the restaurant industry is coming from those who are dining at home.

Customers are increasingly ordering food through apps on their smartphones or by calling in. And that demand for deliveries, from sit-down restaurants as well as the more familiar pizza chains and Chinese take-out spots, is dramatically changing the restaurant industry.

Besides having to redesign restaurants to take delivery into account, the phenomenon is enticing restaurants to modify menus and pick ingredients that hold up well during travel.

In the last five years, revenue from deliveries jumped 20% and the overall number of deliveries increased 10%, according to The NPD Group.
