Mongol Cafe, a small Mongolian restaurant at 842 Geary Street in Lower Nob Hill, had its health permit suspended and was ordered immediately closed on May 4, 2026, following a reinspection by the San Francisco Department of Public Health just four days after an initial routine inspection on April 30. Inspectors found an active cockroach infestation that hadn't been resolved — and uncovered a detail that tells you a lot about how the operator had been trying to handle it: they'd been spraying consumer-grade RAID in a commercial kitchen, which the inspector explicitly told them to stop doing.
What Inspectors Found
The infestation documented in the May 4 inspection report, reviewed by Hoodline, was extensive and multi-generational — meaning cockroaches at every life stage, from nymphs to juveniles to fully grown adults, were present throughout the facility. Four live cockroaches were observed on the wall near conduit, on the refrigerator, on plastic containers stacked on top of the refrigerator, and on the floor. Monitoring traps throughout the kitchen contained numerous live and dead cockroaches. Dead cockroaches were scattered across the facility floor. Two dead cockroaches were found inside a flour container used for food preparation, and one live cockroach was found trapped inside plastic food containers — both of which were voluntarily discarded by the manager on site, per the report from the SF Department of Public Health.
The RAID notation stands out. The inspector's report specifically instructs the operator to "Discontinue using RAID in the facility" — a sign that whoever was managing the pest problem had been relying on off-the-shelf consumer insecticide rather than a licensed commercial pest control service. Under the California Retail Food Code, only approved pest elimination methods are legal in food facilities, and consumer aerosol sprays don't qualify. They also don't work well enough — as the inspection results make clear.
Beyond the roaches, inspectors flagged a reach-in refrigerator running at an ambient temperature of 62°F — more than 20 degrees warmer than the required 41°F maximum. Cut cucumber and cheese stored inside had been sitting at 61–62°F for more than a day by the time inspectors arrived, according to the person in charge on site. Both items were discarded. The refrigerator was tagged out of service and the restaurant was ordered not to store any potentially hazardous foods in it until it's repaired. The hot water at the three-compartment sink was also two degrees short of the required minimum of 120°F, clocking in at 118°F — a small margin that still constitutes a code violation. The handwash sink near the coffee station was blocked by electrical equipment, though that was corrected on the spot.
They Got Pest Control — On the Same Day. It Didn't Help.
The inspector's notes include a telling detail: a pest control report dated May 4, 2026 — the same day as the reinspection — was provided to the inspector. The operator had apparently scrambled to bring in a licensed pest control company, possibly the morning of or right before the reinspection visit. It didn't matter. Multiple live cockroaches were still observed throughout the facility during the inspection, and the closure order stood. The facility, per SFDPH protocol, must remain closed until no cockroach activity is found on a subsequent reinspection. The initial routine inspection that triggered all of this had taken place just four days earlier, on April 30.
Also worth noting: like the Subway closure two days later, Mongol Cafe was operating on a business license that expired on March 31, 2026 — over a month before the closure order was issued.
A Neighborhood Gem With a Complicated Reality
Mongol Cafe occupies an unusual and genuinely valued niche in San Francisco's food scene. As noted by Restaurantji, it's one of the only spots in the Bay Area serving traditional Mongolian dishes made from scratch, including buuz (steamed dumplings), huushuur (fried beef pockets), tsuivan noodles, and borscht. Regulars and visitors alike have praised it on Yelp as a "hidden gem" and a rare opportunity to try authentic Mongolian home cooking in the city. The menu runs from $10 breakfast plates to handmade dumplings and hearty beef stews, priced accessibly for the neighborhood.
The restaurant sits at the intersection of Geary and Larkin — technically Lower Nob Hill, but practically on the edge of the Tenderloin, in a stretch of Geary that's dense with small immigrant-owned eateries and corner operations. It's the kind of spot that a certain type of San Francisco diner goes out of their way to find, drawn by word-of-mouth and the novelty of the cuisine. That reputation makes the current closure more dispiriting: it's not a faceless chain location but a small operator apparently struggling to keep up with a pest problem that has now escalated to a health department shutdown.
What Needs to Happen to Reopen
To get back to serving buuz and tsuivan, the restaurant must eliminate all cockroach activity and have it confirmed by a follow-up reinspection from the SFDPH, according to the department's closure protocols. Proof of professional pest control — not RAID — must be submitted to inspector Usman Javaid before a reinspection can even be requested. The broken refrigerator also needs to be repaired and confirmed capable of holding food at 41°F or below. None of these are insurmountable, but the same-day pest control that still left live roaches crawling around during the reinspection suggests the infestation is entrenched enough to require sustained, professional treatment — not a one-time emergency visit.
