Between pop-ups and dedicated dessert purveyors, doughnuts are having a moment. And fans are already flocking to this just-hatched concept from the team behind the Gallows, which serves fresh-baked treats in a rotating smorgasbord of sweet and savory flavors: Blackberry lavender and lemon coconut have shared menu space with pepperoni pizza and sesame Sriracha. Quirky? Yes. But each inventive new offering (washed down with custom-blend Fazenda coffee) is another fine feather in Blackbird’s cap.
