I go to Baraka often, and it is a fine version of a Sufi style cafe. Good choices of tea, and some of the best medialunas I've had in this city. Since it is a Muslim family, there is no wine or liquor offered. The staff is very friendly, and awfully curious about people speaking English. I won't join you, since I am apparently of the wrong sex, but I do recommend it.
Yes, they do take reservations, and there is one long table in the back.
