Café Diwan. The Tea House is just inside Bab Diwan is one of the best places to sit back and relax in friendly and comfortable surroundings. Cafe Diwan is located in the wall, literally, between Bab Diwan and Bab Kasbah, so it can be reached from either side. The stairs from the street will take you into the main room, but the roof is the place to sit and enjoy the view. Thé with pine nuts (‘pignons) or Café Turc (Turkish coffee) can be enjoyed there, as well as the regular offerings. Cafe Diwan was a fort, Bourj Al Resace, until the arrival of the French in 1881.
