Cuarto de Kilo, the mesquite-fired burger joint that built a following after landing in San Antonio in 2023, has reopened at 12370 Potranco Rd. on the Far West Side, months after quietly closing its original Helotes location. The move puts the chain's giant, rotating-grill burgers back in front of San Antonio fans who had been left without a fix since last fall.
The Helotes restaurant at 12411 Bandera Rd. shuttered in November 2025, according to CultureMap San Antonio, which reports the burger chain is now serving its beastly burgers at the new Potranco Road address. That original spot had opened in June 2023, marking Cuarto de Kilo's first U.S. location after founders Álvaro Aguilar and Miguel Pérez built the brand out of Guadalajara, Mexico, starting in 2010, per San Antonio Current.
From a Family Recipe to 33 Locations
Aguilar and Pérez started the concept using recipes from Aguilar's mother, the same CultureMap report notes, before expanding aggressively across Mexico. The pair opened more than 30 additional locations there before Aguilar set his sights on crossing the border into the United States. The chain has since grown to 33 locations employing roughly 900 people, the outlet's report on the relocation states.
Cuarto de Kilo's calling card has always been scale: burgers cooked over mesquite wood and piled with guacamole and grilled chiles, served alongside a stripped-down menu of fries and onion rings. The signature order is a half-pound barbecue cheeseburger topped with, of all things, more onion rings. The chain cooks it all on what CultureMap describes as its unique rotating grills, a detail that's become part of the brand's identity.
Bigger Space, Bigger Sign, Bigger Investment
The new restaurant sits inside the Grosen Crossing development at 12370 FM 1957, Suite #101, and spans 2,100 square feet, according to San Antonio Current's report on the relocation filing. Cuarto de Kilo planned to spend $350,000 developing the space, with construction expected to wrap on April 1 of the following year, though the filing did not include an official grand-opening date. As the restaurant put it in comments cited by the outlet, the goal was simply moving to a bigger and better location on Potranco.
Along with the new address, Cuarto de Kilo rebranded its signage to lean into its main selling point: the sign now reads big burgers, CultureMap reports. Aguilar acknowledged that bringing the concept to a new market was a challenge, but said the brand emerged from the process having built a stronger team and developed a clearer vision for the San Antonio location going forward.
