The blue plaque for Ho Chi Minh on the site of the former Carlton Hotel, where he worked as Van Ba. It is on New Zealand House in Haymarket. Google maps seems to indicate its on the east side.
Fairly obviously there should also be a plaque on the Drayton Hotel in Ealing where Bac Ho worked in the Kitchen in 1914: https://web.archive.org/web/20101213050535/http://www.ealing.gov.uk/services/leisure/local_history/historic_buildings/drayton_court_hotel.html
