Do you think businesses are helping downtown San Francisco recover?

Super Duper Burgers opened its Union Square location in San Francisco, with Mayor Daniel Lurie cutting the ribbon at the restaurant. The roughly 200 to 300 square foot space occupies the plaza's east-side café.

Why it matters

The city selected the chain as part of its effort to bring more businesses and visitors back to Union Square. The company said a Union Square location would give tourists a chance to try a burger chain that started in San Francisco.

The restaurant measures roughly 200 to 300 square feet and was chosen by the San Francisco Recreation and Park Department over six other food and beverage operators. The city made its selection in January, nearly a year before the opening.
