London is a huge city with an almost unlimited list of potential things to do. While I recommend all of the major tourist spots such as; Big Ben, the London Eye, Buckingham Palace, St Paul’s Cathedral, Tower of London among others, there is more to London then what is within the city center. There are bars and restaurants that are well know in London such as the Punch & Judy in Covent Garden or the Sherlock Holmes restaurant and bar. Along with the tourist sites and pubs there are a vast number of free museums that are available to the public, which cover a wide range of interests, such as the British Museum, Tate Modern, Natural History Museum, or the Science Museum, and can be enjoyable if you are the type of person who enjoys a nice museum. London has the potential to be the best trip that you can have with just a little bit of research about what you may want to do and where you can find it. I do recommend finding a nice tea shop and enjoying some tea and scones.
The potential scale of things to do can make it hard to find something that could really interest you so the city was kind enough to help sort things out a bit with http://www.visitlondon.com it is an easy to use site that can help guide you to what you might want to do for your time in the city.
