You're getting downvoted because somehow people think that restaurant owners shouldn't have to handle basic aspects of operating a business such as establishing a trademark to operate their business under. Without a trademark, what are they going to do if, say, another restaurant opens up a few blocks away with the same name? (And as I understand it, you get some trademark rights just by establishing a business, so you don't have to register the trademark to sue UberEats or Grubhub or whoever)
