NYC's  Health Department inspects about 24,000 restaurants a year to monitor compliance with City and State food safety regulations.
A restaurant’s score depends on how well it follows City and State food safety requirements. Inspectors check for food handling, food temperature, personal hygiene, facility and equipment maintenance and vermin control. 
Each violation earns a certain number of points. At the end of the inspection, the inspector totals the points and this number is the restaurant’s inspection score; the lower the score, the better.​​​​​​​
The following chart shows the city-wide results divided by borough (Yes, there were a few restaurants with as bad result as 160) :
