I live in Manhattan and was hoping to find sliders like those at White Manna in Hackensack, NJ somewhere in the 5 boroughs. I took the bus to meet a friend in Hackensack one day and fell hard for those sliders! I'd like to find a good version a bit closer than NJ. And yes, I've had White Castle before and to me they don't even come close to comparing with White Manna. Thanks so much!
