Boulder's 50 Dirtiest Restaurants (2026): Failed Health Inspections

What the Scores Mean

Boulder's health inspection scoring system rates restaurants on a 0–100 scale. Scores of 90 or above earn an "A" grade; 80–89 earns a "B"; 70–79 earns a "C." Scores below 70 typically trigger immediate re-inspection or closure orders. Every point deducted represents a specific food safety violation documented by an official inspector.
