I've lived in Senegal on and off since the mid 1980s. I have sought good Senegalese food in New York, but was never very happy with what I got.
Because my chow-hound brother was in town, I took him last night to Chez Aunty Libe--a Senegalese restaurant at 6115 Georgia Avenue in DC. It is a restaurant that a Senegalese friend introduced me to. The food was amazing. It is positively the best Senegalese food I have had in the US.
We got the Soupe Kandia (a smoked fish and beef in and Okra sauce), Fish Yassa (fried fish in lemon and onion sauce), Maffe (Lamb in a peanut and tomato sauce), and Manioc leaf stew (pounded manioc leaves with smoked lamb). My favorite was the Soupe Kandia. It came with great hot sauce on the side and a Senegalese drinks made with Ginger or Hibiscus. The food is intense. It is great for anyone who wants a unique food experience.
In short, it is authentic great Senegalese cooking that has had a little of the oil dried out of it for a US audience. Liberata, the owner, is the main cook, she now also has a new Senegalese cook (just in from Harlem a few months ago) named Ramatou. She is great. Everything was cooked to perfection.
