I got some advice today to just get on the tube and pick a random stop to get off - see what is in the area around that particular tube station. This was in response to my saying we had left time unplanned in our itinerary so we could just happen upon interesting things.
We will be spending a fair amount of time between Westminster, City of London, Southwark/Southbank.
So I was thinking about St Pancras but wondered if anyone had advice on particularly good tube stops where close by there are great old churches or other unique sites and maybe even a particularly good pub or restaurant. These would be outside of the areas we will visit like St Pauls, Westminster Abbey etc.
