New guidance from the city of Chicago will allow customers to enter a restaurant and place an order, but says the people must immediately leave after they get their food.
Restaurant and bar owners are now responsible to make sure their customers are following social distancing policies. The restaurant has to make sure people do not congregate inside or outside.
Portillos made the decision to completely close the inside of their restaurants to customers and have opted to rely on a drive-thru only.
"We are ready to feed," said David Manseau, the general manager for the South Loop Portillos. "As you can see, we are moving 60 to 70 cars in the drive thru and orders are going out 6 to 7 minutes."
Manseau said he expects the restaurant to serve thousands of people each day. By using a limited menu, they are able to speed up the process.
The restaurant chain, along with hundreds of other restaurants working with third-part delivery services, are also forming separate pick-up lines with staff bringing food orders to the delivery drivers' cars.
"We are leveraging technology as best as we can in the moment and what we are seeing is that orders are flying out at a rapid pace," Manseau said.
Family owned and operated restaurants have been getting creative to attract customers.
"With every order, we bring a roll of toilet paper," said John Durning from Pizzeria Deville.

"Sunday we crushed it with take-out and delivery because this baby came in handy," Durning said.
Third-party delivery services are also ramping up services to keep drivers busy with some apps adding a no-contact option to minimize contact between drivers and customers.
