I don't understand this response, so I am wondering if I phrased my question badly.
The linked article established that there is no pub in London that can be reached within 60 minutes travel time by anyone starting from any home in any London borough.
I was wondering if there is any other location, be it a coffee shop, a park or even just a point in the middle of a road somewhere, that can be reached within 60 minutes by anyone who lives anywhere in London.
