While eager fans were excited to dine at the place Gaga's parents owned, most seemed less than satisfied with their experience, with one reviewer saying it was "possibly the worst food I've had in New York," and another saying the food was flat-out "horrible."
Gaga has been supportive of her parents venture, at one point attributing her weight gain to the delicious food they served there.
Still, everything Gaga touches does not turn to gold and the negative reviews have persisted.
When the restaurant's health grade was downgraded to from an "A" to a "B" in June of this year, Gaga's father Joe Germanotta took to Twitter to try to defend his eatery, blaming it all on one bad potato in a storage bin and posting the reviewing inspector's name.
Although the restaurant has since had their "A" rating re-instated, patrons complain that it might not be warranted. According to RadarOnline, the restaurant is infested with mice (photos here) and restaurant-goers were horrified as they saw them enter the restaurant and even crawl on tables!
Yikes! That doesn't sound too appetizing...
So far, Joe has not spoken out about the patron's recent claims, but has tweeted that they have been given their "A" rating back and is disappointed that the New York Post didn't cover that the way they did when it was downgraded.
