What can't Facebook do? The social network's newest feature is called "Order Food" and allows a user to order grub from local restaurants. Facebook has teamed up with food ordering services such as eatStreet, Delivery.com, ChowNow and Olo. When you use the feature you'll be shown a list of participating restaurants in the area, and then you can choose pick up or delivery. If you choose delivery with a restaurant that has a partnership with more than one delivery service you will get to choose which service you'd like to use.
