It’s to narrow the search to user-submitted photos on Yelp! (I could have used site:yelp.com to be more precise, but I was lazy.) Otherwise, you get a bunch of advertising and stock-type photos.
Under the circumstances of this thread, I would think those are the ones you want. Are you expecting the advertiser to cover up the way they serve their flagship meals?
Well, yeah. The idealized presentation of a product does not necessarily reflect how it is served. Is this a serious question?
