Yelp has been replacing restaurants' phone numbers with Grubhub-owned numbers, allowing Grubhub to take a cut of orders placed through those numbers. This practice has been criticized by restaurant owners, who claim it is unfair and deceptive. The change was made as part of a partnership between Yelp and Grubhub, which allows customers to order food through Grubhub from within the Yelp app. Restaurant owners are concerned that they are losing profits due to the high fees charged by Grubhub.
