Broad Street -- Pepys often visited this wide road in the City as Capt. Cocke lived here and it also contained the Excise Office, African House and, from 1664, the office and residence of the Navy Treasurer, Sir George Carteret.
In the 1660's Broad Street included what's Fig Street on the 1746 map running NE from Threadneedle St. and not just its extension beyond Throgmorton St. http://www.motco.com/map/81002/SeriesSearchPlat...
