4 . When it comes to eating, more and more Americans are ordering online instead of eating out. In some restaurants, cooks make food for other online restaurants at the same time. Online orders are only 5% of all restaurants orders, but they are growing about 20% each year.

The increase in online ordering in the US has created openings for new kinds of businesses. One is called Kitchen United. It builds kitchens for restaurants that want to enter take-out markets. Chick-Fil-A, The Halal Guys and Dog Haus all have opened kitchens through it. Another company, DoorDash, sends food to customers who order online. Fuad Hannon is the head of new business at DoorDash, He says, “The industry is still young. It may be too soon to know how it will grow, but what we know is that people love to get their favorite food sent.”

Two other businesses, Grubhub and Uber Eats, say their virtual (虚拟的) restaurant programs help small businesses compete. Both reach out to restaurant owners with suggestions for online. restaurants based on data from customer searches. This information helps owners. think about everything from how people get their food to what should go on the menu.

Kristen Adamowski heads Uber Eats. She says they have helped start 4,000 virtual restaurants worldwide, about half of them in the US and Canada.

Virtual restaurants have the benefit of testing new ideas without taking on expensive rents or employing more workers like traditional ones. But small restaurants should look at the risks before starting an online restaurant suggested by third-party app businesses. Those businesses offer no training for kitchen' workers to get used to making new foods. Other things to consider: whether their delivery containers are right for new dishes, or whether they want to increase their dependence on outside delivery drivers. Those are not small or easy things.
