Very hard to prove damages. You would have to prove the calls that you didn’t receive and sales that didn’t happen. There also isn’t any particular “wrong” that has happened unless the restaurant paid money to have a listing and in the terms of that listing there was a clause that required GrubHub not be used. But essentially, paying for Yelp is paying for the service of lead generation which seems to be the exact service Yelp provides. That being said, I detest Yelp.
