A handwritten sign taped to the door at 4540 E. Broadway Blvd. delivered the news that longtime regulars had hoped not to see: C.I. Chu's Mongolian BBQ has shut down for good, closing the book on more than 25 years at the same midtown Tucson address. The sign offered no explanation, just owner Calvin Chu's phone number for anyone who might want to take over the business.
The message was blunt. As Tucson Foodie reports, the sign read, “We are sad to say C.I. Chu's Mongolian BBQ is closed for good.” It also listed Chu's number, 520-370-7144, for anyone interested in reopening the restaurant, according to the outlet.
C.I. Chu's Mongolian Barbeque LLC was incorporated in March 2000, and the restaurant opened that same year on East Broadway Boulevard under Chu, per the same report. The business built its name on a build-your-own format familiar to fans of the genre: guests picked their own proteins, vegetables, noodles and sauces from a lineup of raw ingredients, then watched kitchen staff cook it all together on a large, flat circular grill at high heat. Over the years, the restaurant notes indicate it developed a reputation for consistency and value in a city where that combination isn't always easy to find.
A Shrinking Footprint Before the Final Close
The Broadway location wasn't always C.I. Chu's only outpost. At its peak, the brand also ran a second restaurant at 7039 E. Tanque Verde Road, though that location closed in prior years, the report states. That left the Broadway address as the company's last remaining restaurant heading into its final stretch.
By most accounts, Broadway was one of the last, if not the last, dedicated Mongolian barbecue restaurants still operating in Tucson, according to the same account. No cause for the closure has been confirmed, and no more specific closing date beyond this week's reporting has surfaced.
A Pattern Playing Out Beyond Tucson
Tucson isn't alone in watching this particular style of restaurant disappear. In Roseville, California, O Tasty Mongolian BBQ permanently closed at Westfield Galleria after nearly 15 years in business, according to The Sacramento Bee, with its lease ending in the mall's dining terrace at 1151 Galleria Blvd. That restaurant had opened in December 2009, and the Bee reported it was unclear exactly when the eatery officially closed its doors.
In Boise, the story came with a clearer financial trigger. The #1 Mongolian BBQ location at 6920 W. State St. announced it would permanently close on Feb. 16, 2026, after its landlord sought to raise the rent by approximately 40% ahead of a planned remodel, The Idaho Statesman reported. That chain's original location at 8249 W. Overland Road remained open at the time of that report. Up in Redding, California, Kahunas Mongolian BBQ and Sushi closed on May 9, 2025, after 12 years in business, with owners pointing to the lingering impact of COVID-19 and current economic conditions, according to KRCR.
No such explanation has emerged for C.I. Chu's. For now, the only trace left behind is that handwritten sign on the door and Calvin Chu's phone number, a quiet end for a restaurant that spent more than a quarter-century feeding midtown Tucson one custom-built bowl at a time.
