Fancyapint its been often derided around here but frankly it is the best starting point to find a pub in a part of London you don’t know all that well. So it may not be able to pinpoint somewhere by the street, but it can list a few pubs that may be close your nearest tube station. Unfortunately it does not quite do the required for you Tom, since it appears not to have Oval station in its remit. The search continues.
