"Our goal here is Arizona first," said co-owner Chris Field.
He said 22 of the bar's 26 taps feature Arizona beers, its wine list is 100-percent Arizona, and the cocktail menu uses Arizona spirits, including O.H.S.O.'s Distillery, AZ Bitters Lab bitters, Pedal Haus Brewery, McFate Brewing Company, and Grand Canyon Brewing Company.
The name is also a tribute to the everyday worker.
"Union is an homage to the worker. The Union. The thing that takes care of folks out in the world," he said. "And we're just trying to do that in a restaurant."
The restaurant features exposed I-beams, air ducts and concrete along the walls for an industrial look. It also features a mural composed of three photographs, including the famous 1932 photograph of workers eating lunch on a skyscraper in New York City.
The menu is comfort-style tavern food, Field said.
Guests will find five different burgers on the menu, as well as salads and sandwiches, mac and cheese, and vegetarian meatloaf.
"We're taking classic items and re-imagining them in a fresh, healthy, ingredient-focused way," he said.
