SAN FRANCISCO, City leaders and burger lovers celebrated the grand opening of Super Duper Burgers today, sampling the San Francisco favorite's signature fare at its new location in Union Square, the San Francisco Recreation and Park Department announced.
Located on the east side of the historic plaza in the heart of downtown shopping, the restaurant brings burgers, shakes and indoor and outdoor dining to one of the city's most beloved public spaces seven days a week. Its opening builds on the momentum of Union Square's growing calendar of concerts, festivals and special events. And there's more on the way: La Piazza, a new Italian café planned for the west side of the plaza, is expected to open next spring. Together, the two restaurants will offer food and drinks from early morning into the evening, giving residents and visitors even more reasons to spend time in the square.
"We are accelerating downtown’s recovery and bringing new energy to the heart of San Francisco, and Super Duper opening in Union Square is the latest sign of that progress," said Mayor Daniel Lurie. "When we deliver safe, clean streets and make it easier for businesses to open and thrive, people want to be here. Thank you to Recreation and Park for leading the effort to activate this space and bring a homegrown favorite to Union Square, and to Super Duper for investing in our downtown and in San Francisco’s future.”
"I'm thrilled to welcome Super Duper to Union Square. A delicious burger and restaurant concept born in San Francisco will take the stage in one of our city's most iconic public plazas,” said District 3 Supervisor Danny Sauter. “There continues to be more and more reasons to come downtown and see Union Square in action, be it world-class shops, family-friendly events in the square, or a darn good burger and milkshake."
Founded in San Francisco's Castro neighborhood in 2010, Super Duper has grown into a locally owned and operated Bay Area restaurant chain known for its fresh ingredients and commitment to local suppliers. The Union Square restaurant is its 24th location.
“We've always had our eye on Union Square,” said Edmondo Sarti, Co-CEO of Super Duper Burgers. “Super Duper was born in San Francisco and this city has shaped who we are, so opening in the heart of downtown feels incredibly meaningful. Union Square has been at the center of San Francisco for generations and now it's at the center of an exciting new chapter for the city. We believe in San Francisco, we believe in the future of downtown and we're proud to be part of what comes next.”
The opening follows Rec and Park's renovation of the café space, including the addition of on-site cooking facilities to accommodate expanded food service. The improvements were supported by funding from the State of California's Business and Economic Development program.
“A great public space is a place you want to linger, not just pass through,” said Sarah Madland, General Manager of the San Francisco Recreation and Park Department. “Sometimes that means a concert or a holiday celebration. Sometimes it’s just sitting outside with a burger and watching the world go by. I love that Super Duper gives people another way to enjoy Union Square, any day of the week.”
Rec and Park works with the Union Square Alliance and Biederman Redevelopment Ventures to bring year-round programming to the plaza, from free concerts and community celebrations to seasonal traditions such as the holiday ice rink, which opened Nov. 4.
“We are thrilled to have Super Duper at Union Square Plaza. Union Square has always been a place where people come together to experience the best of San Francisco, and this exciting addition brings even more energy, flavor, and vibrancy to the heart of our city,” said Marisa Rodriguez, CEO of the Union Square Alliance. “With incredible local businesses like Super Duper joining our community, alongside exciting activations and programming, the plaza is becoming an even more dynamic and welcoming destination. Each new addition builds on the momentum throughout Union Square and helps create a public space where residents and visitors can gather, connect, and enjoy all that makes San Francisco so special.”
Super Duper Burgers is located on the east side of Union Square along Stockton Street and is open daily from 10 a.m. to 9 p.m.
