Korean fried chicken is some good stuff!
The place that you're talking about is Mad For Chicken on 5th Ave btwn 32nd & 31st. Kyochon is opening soon right across the street at 32nd and 5th.
There's a good number of Korean fried chicken places in the metro NY area, mostly in Queens or NJ.
The New York Times did an article on this a while back:
