The Bus Stop Cafe on Tower Bridge Road has been taken over by the people that run the fab grocer's opposite. It's still a standard cafe with builder's breakfasts and sandwiches but they have a short North African menu too. I've been three times in the last week and had lamb tagine, merguez and salad and chicken cous-cous. The place is unchanged inside but the Moroccan stuff is as good as any I've had and the staff are the friendliest on the street. Cheap too.
