Where in the world would you park?
No one drives to these things because you can't park.
You can't park anywhere!
My elderly and wobbly parents visited and wanted to see Borough Market, after much circling and trying to park and failing to find any spaces or any of the car parks advertised and getting lost and misdirected, after nearly 45 minutes I dropped them off, drove home and parked outside my house and walked up (20 minute) to meet them.
Then I had to walk back, collect the car and go and pick them up.
You can't drive anywhere in central London unless you are rich enough to employ a chauffeur to sit on the double yellow lines for you as you see them doing in Covent Garden on a Friday and Saturday night.
