It's unclear who is behind the coffee shop. Dumb Starbucks is able to use the Starbucks name and logo because it is technically "making fun" of Starbucks and is considered "a work of parody art," according to a Dumb Starbucks letter.
Under the law, Dumb Starbucks is not a coffee shop but an art gallery, the letter says. "The 'coffee' you're buying is considered the art," the letter says. "But that's for our lawyers to worry about. All you need to do is enjoy our delicious coffee!"
