The first thing you notice when you walk into a Sweetgreen Infinite Kitchen store is that no one is preparing your salad. The components—rows of precisely portioned proteins and toppings behind a glass panel—are present, but the assembly is carried out by a machine that moves with a level of focused precision that human line workers, no matter how trained, can’t quite match at volume. 500 bowls in an hour. uniform distribution of dressings. No chicken that is not properly portioned.
Staffing fast-casual restaurants is one of the more consistently difficult operational issues in American retail food since the machine doesn’t fatigue, doesn’t call out sick, and doesn’t require management through a labor market. When Wall Street finances the new wave of fast-casual restaurant businesses, it is actually purchasing this rather than the brand, menu, or Mediterranean-inspired flavor profile. What occurs behind the counter is the subject of the wager.
On the surface, CAVA’s June 2023 IPO was a restaurant company going public. At $22 per share, it caused the typical skepticism among analysts on whether a business with fewer than 300 stores could support a value that suggested it would become the next Chipotle. The more upbeat read realized that CAVA was essentially a story about operational efficiency dressed as a culinary brand rather than a restaurant.
In August 2025, CAVA declared that it will provide up to $10 million to Hyphen, an automated makeline developer based in San Jose that Chipotle had previously invested $15 million in through its Cultivate Next fund. With this action, CAVA officially entered what Restaurant Business aptly referred to as “the fast-casual automation arms race.” Hyphen’s under-counter makeline technology, which manages digital and delivery orders concurrently with human in-store service—basically tripling throughput without doubling headcount—is currently being tested by both chains.
The events of late 2025 have made Sweetgreen’s Infinite Kitchen tale more intricate and fascinating. In addition to obtaining a supply and licensing agreement that permits Sweetgreen to keep opening Infinite Kitchen restaurants at cost plus about five percent, the company sold Wonder Group its Spyce technology subsidiary, the business unit that had created the Infinite Kitchen automation, for $186.4 million. Through the sale, Wonder received the manufacturing and innovation investment while Sweetgreen’s R&D burden was eliminated from its financial sheet.
As Wonder makes investments to make the technology more affordable and efficient at scale, CEO Jonathan Neman told analysts that the agreement should eventually lower unit construction costs. At the time of the sale, twenty Infinite Kitchen units were in use, and more were planned. Compared to typical Sweetgreen restaurants, the sites were generating quantifiably greater profits and reduced labor costs. The technology is functional. Sweetgreen has lowered its unit growth objective from 35 openings in fiscal 2025 to 15 openings in fiscal 2026, raising the question of whether it can scale quickly enough.
The Wall Street justification for all of this is straightforward: automation reduces labor, which normally accounts for 25 to 35 percent of fast-casual income. Food cost variance is decreased by maintaining portion consistency across hundreds of locations. Automation-equipped restaurants can capture lunch crowds that would impede a traditional line thanks to higher throughput without corresponding increases in labor. Less is known about the consumer side.
Although office workers have consistently demonstrated a willingness to pay $14 to $18 for a fast-casual bowl, the potential market is limited. Sweetgreen is experimenting with wraps that start at $10.95 in an effort to attract clients who are turned off by the typical pricing range. It’s really questionable if the automation narrative will continue if these chains expand into lower-income markets and more challenging economic times.
It’s difficult to ignore the Chipotle analogy that permeates every discussion of CAVA and Sweetgreen. After becoming public in 2006, Chipotle overcame years of doubts about its ability to grow beyond a niche and went on to become one of the greatest restaurant success stories of the previous 20 years, proving that consistency at volume and quality could coexist.
Although neither CAVA nor Sweetgreen have yet to equal Chipotle’s unit economics, footprint, or margins, they are both using that model. A portion of the automation investment is an effort to close that gap without the decades it took Chipotle to establish. The next few years’ worth of earnings calls will reveal if it operates that way or whether the disparity endures regardless of what occurs behind the counter.
