Old Boma is conveniently located by the Zanzibar ferry terminal and we dropped in after our ferry docked. It was difficult to navigate to as there are major roadworks happening outside and so we entered via the rear gardens, where people are seated eating - seeming to be from local businesses. After asking, a waitress took us into the old building - apparently the sultan's former guest house (his actual house had been demolished nearby to make way for the towering Johari hotel. Once we reached the roof garden, unfortunately they only had white rice, which we ordered with barbecued chicken. The rice was ok, served with some rather bland beans, although the chicken was really good and so we ordered another portion, that was not quite so good and the cold chips it was served with pretty poor - the food being run up the stairs from the kitchen in the garden below. It does serve beer, and I enjoyed a Safari. There are nice views from the roof.
