Joanne Trattoria on the city's West Side restaurant was smacked with a shameful 'C' grade, the lowest possible rating, after health officials uncover its filthy habits, reported Daily Mail online.
Any restaurant racking up 28 or more violation points gets stamped with a 'C' and Gaga's was found to have a staggering 42, six of them 'critical'.
According to the report published by the Smoking Gun, the clean team visited the restaurant, run by Gaga's parents Joseph and Cynthia Germanotta, on October 2.
The Gotham eatery first fell foul (literally) of health standards less than one month after its launch in February, scoring a boarder-line 'C' with 31 violations.
Now, the health officials discover that the restaurant has no hand-wash basins in staff toilets.
"Hand washing facility not provided in or near food preparation area and toilet room," the report reads.
"Hot and cold running water at adequate pressure to enable cleanliness of employees not provided at facility. Soap and an acceptable hand-drying device not provided," it added.
Other health crimes committed by Joanne's included staff wearing filthy clothing and no hair nets.
Surfaces were left unwashed, officials found, food not protected from contamination and kitchen workers abandoned utensils in favour of their hands.
