Visiting London in four days

I've been in London the last weekend and this is the way I've done to visit this amazing city.

I've flight with Easyjet for the first time and it has been a nice experience. In its website I reserved the hotel too. My hotel was Park Plaza Sherlock Holmes, in Baker Street near the underground station which is very important in London. But it has been a little deception when we have seen the room which has nothing to do with the photographs in its website. If you go to Gatwick Airport is important to buy a Gatwick Espress ticket before flying. This train arrives to London in 30 minutes without stops up to Victoria Station in central London. In the same Victoria station catch the underground (before that you must buy an economic Oyster Card, so you don't need a ticket every time you catch the tube).
The tube (London Underground) is very easy to understand. There is a lot of lines that cross London form North to South and East to West, so you only need to know clearly where you go, look the map (the colour or the name of the line) and take a direction (Northbound, Southbound, Eastbound or Werstbound). The indications are clear and the underground is very secure and populated, sure the best option to move in London.

Thursday:
We arrive in the afternoon, take the tube to the hotel, and tube another time to Oxford Street, dinner in Soho, visit Picadilly Circus and come back to the hotel.

Friday:
We cross Regent's Park (I love all the big and green parks London has) up to Camden and visit Camden Market. Tube to London Tower, cross Tower Bridge, visit St. Paul's Cathedral (it's a surprise in London you must pay a lot to enter a Cathedral and you don't pay in the museums). Cross the Thames for the modern Millenium Bridge and visit to Tate Modern Museum. Tube to Covent Garden , walking to Trafalgar Square, lunch Fish and Chips. Leicester Square and arrive to the Dominion Theatre in the Tottenham Court Road Station and buy tickets for the Queen musical "We Will Rock You" (Great!!!). After that you can visit the British Museum (a must). Rest a little in the hotel. Go for a walk to Notting Hill and dinner in Pizza Express (very good pizzas). And finally we went to a pub to drink some Guiness beer.

Saturday:
Breakfast in Starburcks (fine!).
Green Park, Buckingham Palace, St. James Park (lovely squirrels), Webminster Abbey, Big Ben, House of Parliament, London Eye (very big queue, I've no time to get on), vegetarian Lunch and good company in the London Fo Guang Buddhist Temple, come back to the hotel for the incredibly crowded Oxford Street, prepare yourself to go to Queen Musical (We Will Rock You): Amazing!

Sunday:
Hyde Park (more squirrels), Museums (History, Science), Harrod's, Lunch at Royal China Seafood Restaurant in Baker Street and go to the airport. Go with time, I found a great easyjet queue to check-in, and nearly lost my flight!
