Firstly, don't forget to take double decker excursions. The excursions take you to some interesting places, and you can even ride on top of the bus!
Then, you can get to see the Buckingham Palace. Here, Queen Elizabeth II (now dead) lives here, she even has her own room! Royalty rules!
Also, we didn't forget about Big Ben. The clock tower is connected to another tower, and it's a base jumper or skydiver's big dream!
Then, Trafalgar Square and West End. It has lots of stores, buildings, and theatres.
Finally, you can go to any chip shop. Here, the fish and chips served here taste and smell good. Yum!
Oi mate, the bit about Buckingham and the Queen gave me a good chuckle. Just so ya know, Buckingham Palace tours are only sometimes available coz the royal fam's still using it. Also, Big Ben's not really for base jumping, right? You might want to mention the actual tours of the Houses of Parliament when they are on, absolutely fascinating stuff if you're a history buff.
