Depends what you are interested in... I can't help you other wise
For arcades and entertainment, visit the Trocadero, Leicester Square and Soho (all next to each other)
For museums visit the Science, Natural History, Victoria and Albert, and the British Museum (there are thousands of museums, but those are some of the main ones, and I'd def recommend the Nat History).
For Art Galleries, I'd recommend the National Portrait, National Gallery, Tate Britain, Tate Modern, Serpentine, and White Cube
For British empire world dominating history visit Greenwich Observatory, Kew Gardens, and the HMS Belfast
For "London" things, Buckingham Palace, Trafalgar Square, Tower Bridge, Tower of London, St Pauls, and Houses of Parliament
For shopping, visit Spitalfields Market, Camden Town (specifically Camden Lock), Covent Garden, Regents Street, Selfridges, Harrods, Soho again.
For parks try Hyde Park, Victoria Park, and Regents Park. Regents had London Zoo, apparently the worlds first zoo or whatever. It's pretty good.
For something a little different, visit Shakespeares Globe, Brick Lane, the Olympic stuff
I've lived here for two and a half decades, and I see new shit every day. It's nice to try and cram it all in, but honestly, it would take an absolute lifetime. This is a huge, rich city, vibrant and full of culture. I hope you enjoy your visit, and maybe just walk around for a bit. There are Tube stations all over the spot, so it's easy to not get lost.
Advice: If a pub charges more than £3.20 a pint, it's a tourist trap. Run away. Try and get to the theatre, it's world class. Most of what you'll be doing will involve the centre of London, and most of it is a short walk from everything else, so try and walk rather than rely on the Tube.
Weekdays, the Underground charges more before 9.30am... a LOT more. So don't bother before then. Buy a travelcard, it'll cost less in the long run.If you are interested in museums, the Natural History, Science Museum and Victoria and Albert are RIGHT NEXT TO EACH OTHER. Literally. They are also a bit out of town, so do them all in a day.
Message me for info on any of these things, or more, if you can tell me exactly the sort of holiday you are looking for XD I like making sure people have an excellent first time here
