Score
Across the available record, Thai Oishi has 17 inspections on file, the first dated 2022. Inspectors last stopped by on Feb 25, 2026. When a facility lands in the low risk tier, it usually means nothing alarming showed up at the most recent visit.
Recent visits have flagged more than earlier ones: around eight violations per visit lately, up from roughly two violations before.
The pattern that stands out is “(p) person-in-charge-duties”, which has been cited seven times.
That puts the facility ahead of the local pack: the average Dorchester restaurant scores 86. The record is unremarkable in either direction.
