You can now get a burger — or a chicken sandwich — from well-loved local chain Super Duper in Union Square Plaza.
Super Duper opened its 22nd location on Tuesday in SF's Union Square, in the kiosk on the Stockton Street (east) side of Union Square Plaza. The opening brings life back to this kiosk, which in recent years had housed a sort of nondescript cafe, and which had been slated to be an outpost of Tyler Florence's Miller & Lux Provisions, until that plan fell through last year.
We learned back in January that SF's Recreation and Park Department had selected Super Duper to take over the space, choosing them over six other vendor applicants.
As the Chronicle notes, the barely 300-square-foot kiosk is Super Duper's smallest location to date, and is mostly just a counter operations with outdoor seating on the plaza.
The menu includes five beef burger options — including a new truffle burger — as well as a veggie burger, a grilled chicken sandwich, a grilled cheese sandwich, and a breakfast sandwich that will be served all day. You can also get a BEC (bacon, egg and cheese) Burger, if you want more than just a BEC.
There are also fries, of course, and milkshakes made with Straus Family Creamery soft serve. And just in time for the ice skating rink to open, there is a seasonal special peppermint hot cocoa-flavored shake now available.
Mayor Daniel Lurie was on hand for the ribbon cutting and grand opening Tuesday afternoon, and enjoyed a child-sized milkshake that he said was "delicious."
On the other side of the plaza closer to Powell Street, the kiosk that has been home to b. patisserie for much of the last two years will become La Piazza, an Italian espresso and pizza bar, starting in March 2027, after b. patisserie departs. As we learned last month, it is a new venture from the family behind Colibri, the Mexican restaurant that was formerly on Geary Street near the plaza, and now lives in the Presidio.
But for now, you have a few months left to get b. patisserie croissants and kouign ammans in Union Square Plaza and, just steps away, get a Super Duper burger as well.
Super Duper continues expanding across Northern California, and just over the summer the chain opened its 21st location in Japantown/Lower Fillmore, in a former Burger King at Fillmore and Post.
Super Duper first launched in 2010 as SF's answer to Shake Shack, with its first location in the Castro neighborhood.
