I visited London (along with Amsterdam and France) in the summer of 2010. This was also the time during the World Cup so nevertheless, there was a lot more excitement in the streets in soccer (football) mad Europe. I did watch a match in a pub in England (item on bucket list checked off).
When I wasn’t in a pub having a pint (which was 80-90% of the time), I did the touristy thing of seeing Buckingham Palace, Tower of London, Westminster Abbey, St. Paul’s Catherdal and so forth. So much history in London that it becomes so overwhelming that you may need to head back to the pub for a nightcap.
