What it is

Why walk here for the coffee
It is the closest thing of any significance to this café — nearer than the market, nearer than the metro. Do the museum first, indoors, while the ward is at its hottest; the walk back is two minutes, and the room at the end of it has air conditioning, free Wi-Fi and space to sit for an hour without being moved on. We open at 07:00 and close at 23:00; the museum's own hours are on its door.
