Google quietly announced in their release notes for the Google My Business section that some businesses can now add "action URLs" to their business profile specifically for "online orders or reservations" and similar actions. Google said it will "make it easier for customers to take action directly from your listing."
It seems like an easier way for businesses to understand the URL attributes they had before.
In any event, Mike Blumenthal posted pictures of some businesses that has this option. Note, it depends on how your business is classified, not all businesses allow online ordering or reservations.
