An audience gathers around the transparent 14-foot-long "culinary instrument" in a restaurant called in San Francisco's SoMa neighborhood.

Brioche buns are sliced, buttered and toasted by paddles moving like waves in the ocean. They land in specially designed, compostable hamburger boxes. The buns are topped with fresh produce, sourced from local farms, which is sliced on the spot. Cheese is shredded from blocks and added. The in-machine meat grinder has been calibrated to vertically align the meat with diner's incisors. The 4.5-ounce beef patties are ground from brisket and cooked using the induction method, both sides at once, then slid into the boxes.

And the fumes from cooking? They are cleaned inside the machine.

The sleek hamburger-producing machine, featuring organic curves and copper detail, fits in perfectly with Creator's airy 2,200 square-foot space, white walls and high ceiling. It attracted a waitlist this summer for its bi-weekly lunches, and will open full time in September. It fits with the city as well — the restaurant is just two miles away from where the Elon Musk-founded OpenAI lab recently tested a robot hand named Dactyl.

Creator's parent company is a culinary robotics firm founded by 33-year-old Alex Vardakostas, who grew up in the burger business in Southern California. "I really got going on the griddle when I was like 14, 15," says Vardakostas, whose family owns the two Orange County locations.

The inspiration struck Vardakostas while he was a junior at the University of California, Santa Barbara, studying physics. He woke up at 4 a.m. with the idea for a robot-made burger. "A lot of people don't talk about this or realize it, but it is incredibly unhealthy — inhaling grease-laden vapors and soot all day. So that was this really exciting idea for me, where I could just have this beautiful instrument and I could take control of it," says Vardakostas. (The World Health Organization has identified a number of hazardous compounds released into the air by cooking, and while many oven hoods in commercial and residential kitchens filter some of the bad stuff out, some do a better job than others.)

Since then, Vardakostas has focused on creating a healthier work environment and developing a better way to make high-quality food at a reasonable price. Four years after he had his bot-burger vision, he built his first hamburger-making robot in his childhood garage. "I would drive up to Menlo Park and get machine parts at TechShop and drive all the way back down to Orange County and hope they fit together and try to make it work," he says.

A move to San Francisco and a collaboration with 32-year-old Steve Frehn, now Creator's co-founder and COO, led to the second rendition of the burger machine. Now on version four, the machine, comprised of food-safe plastic tubes and over 350 sensors run by software and 20 computers, is fully operational. It is stocked with carefully sourced produce, bread and meat.

David Bordow, 32, culinary lead and experience designer, emphasizes the importance of quality and carefully chosen seasonal ingredients. "The philosophy is, 'Let's find the best stuff that is available,' " he says. The beef is antibiotic- and hormone-free, sourced from , a family ranch owned co-op.

At Creator, there's more to the staff than just a robot. All burger sides are human-made. The obligatory fries are on the menu, along with seasonal salads and vegetables.

There are currently four kinds of burgers, including the Tumami, created by Top Chef's Tu David Phu, which features an oyster aioli and shiitake mushroom sauce.

Eventually, customers will get to control how much sauce and seasonings they want the robot to add. "The nice thing about using a machine is that it's very precise, so if someone has a sodium limit, or something like that, we can track that sort of thing and provide a little customization," says Frehn.

In a city of pricy boba drinks and marked up avocado toast, Vardakostas says Creator's mission is to improve food quality and make it accessible. Burgers are $6. "We want everyone to be able to partake," he says.

Word is spreading. Los Angeles-based high school student Moses Rosales heard about Creator on YouTube and convinced his mom and aunt to dine there during a two-day trip to the Bay Area. "It was amazing to see how a robot made a burger," Rosales says. "I didn't know how far you could go with it. Now I'm seeing it's a really high-end burger."

For now, Creator is the only home to two burger-making robotic machines, although Frehn says they hope to expand.

On the ground floor of the San Francisco building that's also home to offices for Microsoft and Riverbed, approximately 10 Creator staffers worked the soft-launch lunch shift this summer. Employees, who start at $16 an hour, are allowed to spend 5 percent of their time on the clock reading or learning a new skill. Bookstore-style "staff picks" fill the three bookshelves, with titles including Alice Waters' The Art of Simple Food and Michael Pollan's The Omnivore's Dilemma.

Creator is focused on the service and culinary side of the business, too. "We've been pretty firm about not having an automated ordering process, with kiosks or something like that," says Vardakostas. "So we have people, and that costs us money. But at the end of the day, that makes for a better guest experience and it's a more human-centered restaurant."

Creator is not the only restaurant to feature a food-making robot while also making an effort to retain its humanity. has three San Francisco locations. Each features a robotic coffee-making arm that can produce drinks in 30 to 40 seconds. Customers retrieve their beverages by punching in a texted code sent to their phone.

Opal Franklin, a recent college grad working at the Market Street Cafe X location, walks the small space on a Friday afternoon. She offers customers and curiosity-seekers oat milk samples before explaining, "Often times people say that we take away barista jobs, but we in a sense shift the job. The robot is very precise and it's very practical, so we have a product specialist on site to answer questions and help people out and make it more humanistic."

While still in their early days, culinary robots are starting to pop up beyond San Francisco. In nearby Silicon Valley, delivers pies pressed by a "Doughbot" in nine seconds. Across the pond in Paris, startup has created a three-armed robot that makes pizzas from start to finish. On the East Coast, four MIT grads opened in Boston in May, which features robotic tumbling woks that create customized bowls, under the culinary direction of renowned French chef and restaurateur Daniel Boulud.

While the culinary robotics show at Creator wows, this isn't a novelty to the team. "We put a lot of care and effort into making sure this would have a positive effect on consumers," says Frehn. "And we worked to create a better retail job as well."
