@nwinezog Google started to test online delivery late 2018. Grubhub is not (yet?) supported but if the restaurant partners with Postmates, Doordash and/or a few others, this CTA will automatically appears.
To be removed, you need to close your Postmates/Doordash account. My understanding is that they send a feed to Google that automatically activates this CTA. Google won't remove it unless the delivery page on the partner is removed. Google receives a new feed every 7 days so it would take a week for the CTA to disappear. Online delivery platforms don't play fair asking permission and don't offer options to be or not in that feed.
