Dibiteries sell the lamb by weight: customers choose the meat, it goes on the grill, and it comes back chopped and wrapped in paper with onions, mustard and bread.
Chunks of lamb or mutton marinated and grilled over hot coals until charred outside and juicy inside, chopped up and served with a sharp onion-and-mustard sauce. It's the specialty of dedicated grill stalls known as dibiterie, which come alive at night across Dakar.
