The sizzle of grilling meats and an aromatic twist of lime are drawing lines around the block on Mill Avenue in Tempe, as food enthusiasts queue up for the world’s only Michelin-starred taco pop-up. Renowned Mexico City chef Mario Hernandez Alonso has rolled up his sleeves to serve up his signature tacos to a hungry Arizona crowd. The El Califa de León pop-up, which commenced on Cinco de Mayo, has become the latest food frenzy, according to Phoenix New Times.

Local supporters, arm in arm with curious food tourists, are spending hours waiting to dig into tacos priced at $10 apiece. Despite some complaints about the cost, the pop-up claims to deliver value, offering a hearty portion of meat on each 5-inch tortilla. For those seeking to skip the cross-border trip to savor such Mexican delicacies, this event has been positioned as a unique dining alternative. Public interest peaked following Michelin’s labeling of the experience as "elemental and pure," an endorsement that has clearly resonated, creating visible ripples on the Tempe food scene.

The brainchild behind this culinary cross-pollination is GrinGO CEO Brian Krupski, formerly a Mexico Affairs Advisor for the Arizona-Mexico Economic Council. By leveraging his connections, Krupski not only transported a slice of Mexican culture to the States but forged it with Arizona’s reception of Aeroméxico’s direct flights to CDMX from Phoenix. Mayor Corey Woods of Tempe took honor in tasting the first taco, a move that cemented the pop-up as more than just a gastronomic gathering. As reported by WorldClass, it's a celebration of Mexican heritage and the power of food as a cultural bridge.

Partners for the event, WorldClass, have ensured that only premium cuts, such as Devesa’s grass-fed tenderloin and short rib, and Fermín’s Ibérico pork loin are used. The intent is to transform a simple taco into a Michelin-level indulgence, with rich flavors and textures that elevate this street food to a culinary showstopper. And with the event’s closure looming on June 3, according to WorldClass, the taco pop-up in Tempe is indeed an offering not to be missed.

El Califa de León's pop-up continues to operate from 4:00 p.m. to 10:00 p.m. on Monday and Tuesday, as confirmed in both Phoenix New Times and WorldClass reports, respectively.
