Is Oso clean?

Oso currently carries Grade A ⏳ from NYC Department of Health and Mental Hygiene (DOHMH). It was posted on May 8, 2024 and still stands. The place has been inspected again since — on November 21, 2025 scoring 34 points — but NYC Department of Health and Mental Hygiene (DOHMH) has not ruled on that visit, so no new grade has been issued. Inspectors wrote up 4 critical violations — the kind most directly linked to foodborne illness. On Cooked's ladder the posted grade reads clean 😇; the numbers above come from the newer visit.

How New York grades restaurants

New York City health inspectors score violations in points, and lower is better: 0–13 points earns an A, 14–27 a B, and 28 or more a C. Every restaurant is inspected at least once a year, and the letter has to be posted in the window. A restaurant that scores 14 or more on the first inspection of a cycle does not get a letter right away — it stays “Grade Pending” until a re-inspection settles it, which is why some spots here show an hourglass instead of a letter. Cooked only ever shows a letter the city actually posted; we never infer one from a score.
