please make it lively as if you were really giving a recommendation or advice;
thank you very much !
In London, you can see monuments, for example : Big Ben, Tower Bridge, the crown of the Queen in the Tower of London and the Houses of Parliament. You can visit the capital by black cab or double decker bus.
As a souvenir, you can buy a British tea set, a small phone box or a British Guard figure. Don’t forget to take your umbrella : it often rains in England !
