Been here twice now and both times it's been amazing.
Time 1 (girlfriend's birthday) : we got the flatbread and the chickpea hummus and red pepper Muhummra to share and i got the calamari appetizer. The latter was very solid but the made in-house flatbreads and the hummus and muhummra (positive i'm misspelling that) were amazing. She got the duck for her main course and i the Double Cut pork Chop. Both were amazing but her Duck really stole the show. We then got a desert (by surprise for her) of the flourless chocolate cake, which we both all but melted over.
Second time, returned this past weekend with the Girlfriend and her parents. The flatbreads and same hummus and muhummra combo drove rave reviews again, as did the butternut squash puree. It was the Half Chicken my girlfriend and i each had, as well as the meatballs and brussels sprouts dish her dad got and the lamb her mom got, that were the stars though. The chicken fell off the bone and tasted amazing, essentially cooked to perfection. I'd go back again just for the chicken.
Casbah has become a fast favorite in this city, in particular for when company is in town or i feel like treating myself a little, and i have a feeling it will remain in that category for a long time.
