The only West African restaurant along this stretch of Adam Clayton Powell is Keur Sokhna, but I'd peg its chow as Senegalese:
Just to the north is Yatenga, which supplanted the late La Marmite. Though it's named for a province of Burkina Faso, the menu looks to be straightforward French bistro, and the clientele, principally young European tourists.
