White Mana Diner in Jersey City
I always heard about this place how it is a NJ staple with best sliders for over 70 years. I pass by at least few times a month but I never stopped by until recently.
I ordered special (3 sliders and a "best lemonade in NJ"). What I received had practically no meat. Just some cheese. Arguably worst food I had in NJ and by far worst slider/burger I ever had no matter the state/county/continent.
I should have known better. Place never looks busy and it was empty when I walked in. Only owners sister and two workers. Few people came in while I was there and none of them ordered sliders.
Honorable mention to Rutt's Hut in Clifton. One more "famous NJ staple" with terrible food that is always empty.
