Walk the oval at noon these days and you'll pass more foot traffic than the block has seen in years. You'll also, if the timing is right, pass a robot.
It's not a metaphor. A humanoid unit nicknamed Pam, deployed by the robotics company OpenMind, has been spotted circling South Park's historic lawn on a regular basis this year, part of a wave of AI and robotics firms that have quietly repopulated the offices ringing the park. Erwin Ganschow, who has run the counter at Caffe Centro since the early 1990s, calls the robots "semi-annoying." He also reads them as a good sign. More workers nearby usually means more people walking in his door.
Here's the part that surprises people who haven't been paying close attention: for all the office activity, Caffe Centro is still the only sit-down restaurant operating around the park. One cafe, serving a block that used to support several. If you've noticed the neighborhood feels fuller but your lunch options haven't grown to match, you're reading the situation correctly. The money came back to South Park well before the restaurants did, and that gap is the real story of the block this year.
The Money Came Back First
South Park's office roster reads like a partial list of the Bay Area's active venture capital. Flourish Ventures opened its San Francisco office at 140 South Park back in 2022. Touring Capital followed in 2025, announcing a South Park address alongside a $330 million fund focused on AI software. Notable Capital and the investment firm Coatue both now list offices at 21 South Park, and Founders Circle Capital and MGV operate within walking distance of the oval.
Cameron Tu, a broker at Touchstone Commercial Partners, describes the block plainly: South Park today is primarily an office market. Rents per square foot have climbed, pushed by early-stage startups flush with venture funding. Retail, in his telling, is a different animal entirely, weaker and considerably more volatile. He's watched at least one prospective restaurant tenant sign a lease around the park and then default before opening.
That's the mismatch in a sentence. Capital moved fast. Storefronts didn't follow at the same pace.
One Cafe, Two Empty Rooms
Caffe Centro's survival wasn't inevitable. Ganschow has watched the block cycle through boom and bust since the small tech startups of the late 1990s and the dot-com frenzy that followed, and then the crash that turned the park, by some contemporary accounts, into something close to ground zero for tech layoffs. The Butler and the Chef, a French bistro that once anchored the block, didn't make it through that downturn.
Caffe Centro did, in part because its landlord, the affordable housing developer Mission Housing, took an unusual risk and let the staff reopen the place as a worker-owned collective in 2024. It still doesn't look like a place built by a branding agency. The interior is wood-lined and a little worn in, the menu simple and relatively affordable, a contrast Ganschow draws deliberately against the corporate cafe aesthetic of the Blue Bottle a block away on Second Street. He's noticed young tech workers responding to that difference rather than avoiding it.
"They seem kind of interested in this place because it's not like your normal Apple Store-type cafe," he told a Mission Local reporter this past July.
Ganschow is careful not to call it a boom. What he'll say is that the tables are fuller, midweek lunches are busier, and he's been able to hold prices where they are while still covering the bills. "There's a light at the end of the tunnel," he said. It reads as cautious optimism from someone who has seen the block promise a comeback before and watched it stall.
Meanwhile the space that once held Mexico Au Parc sits empty, one of the visible gaps in a block that otherwise looks like it's filling in.
The Bakery Everyone Keeps Asking About
The other gap has a name attached to it now. Flour & Branch, the bakery Lauren Arnsdorff started as a delivery-only operation during the pandemic before opening a storefront on Third Street, has been working on a second location at 155A South Park, in the space that once held the Butler and the Chef. The move comes with a revamped concept, a full sit-down bakery-cafe with brunch service, supper, and a courtyard chef's table tucked away from the main room.
As of the most recent reporting in mid-July, the opening was still described as planned rather than confirmed, a modest delay from the midsummer timeline the shop had floated earlier in the year. For a block that's been down to a single restaurant for a while, a second sit-down spot from an operator with an existing following in the city is the kind of addition that changes the daily math for anyone who works or lives nearby. Lauren Arnsdorff has said passersby regularly stop to tell her the park needs another restaurant. Ganschow, for his part, welcomes the idea outright. More restaurants around the oval could give office workers a reason to leave their desks, and maybe a reason for people outside the immediate block to come in at all.
What This Actually Means If You Walk the Oval
None of this is a story about a neighborhood arriving. It's a story about a neighborhood arriving unevenly, and the unevenness is worth understanding if you spend any part of your week around the park.
The office side of South Park has genuinely refilled. Capital is flowing, rents on the commercial side have risen accordingly, and there are more people working within a five-minute walk of the oval than there were a few years back, robots included. But the retail and restaurant side hasn't caught up at the same speed, and that lag shows up in small, specific ways: a single restaurant carrying the whole block's lunch traffic, a storefront that's stood empty since a tenant defaulted on a signed lease, a beloved bakery's brick-and-mortar debut running behind its own announced timeline.
If you already live in this pocket of San Francisco, you've probably felt this without naming it. The park is louder at midday than it was a couple of years ago. The dog walkers and lunch crowds have a bit more company. But you still can't just wander over and get a table at more than one place, and that's not going to change until the retail side of the block closes the gap the office side already has.
Worth watching, if you're keeping an eye on the block: whether Flour & Branch's opening actually lands this fall, and whether the vacant space that once held Mexico Au Parc finds a tenant that sticks. Those two storefronts, more than any VC press release, will tell you whether South Park's comeback is becoming a complete one or staying office-only for a while longer.
A few blocks northeast, the city is pouring capital into the neighborhood too, with the Gene Friend Recreation Center undergoing a $40 million rebuild across an expanded footprint between Sixth and Seventh, Howard and Folsom, expected to open this fall. It's a different kind of investment than a venture fund, but it's another sign that this stretch of SoMa is getting attention from multiple directions at once, not just the tech money circling South Park's oval.
For now, if you're headed to the park for lunch, plan for Caffe Centro, keep an eye out for Flour & Branch's doors finally opening, and don't be surprised if a robot crosses your path on the way.
